    I have some trouble figuring out the part numbers for some of the attaching parts on my 1997 Mitsubishi Eclipse Spyder GS-T.
    There are a few places in the engine bay where it looks like something is supposed to be attached as well.

    I am using an online parts catalog by VIN.
    I also check two other online catalogs by VIN as I have noticed there are small inconsistencies between them.

    We can start off with the front exhaust pipe.
    There is obviously supposed to be two bolts there, but one is gone.
    What is the part number for this bolt?

    The parts diagram shows only one bolt at this location.
    The part number for that bolt is MF244884.
    It also says the quantity required is one per car.

    I am confused.
    This is obviously incorrect.
    I must have misunderstood something.

    Any help would be appreciated.

    I am still confused.

    As mentioned in my first post:
    The parts diagram shows only one bolt at this location (see attached photograph Exhaust Pipe & Muffler).
    The part number for that bolt is MF244884.
    It also says the quantity required is one per car (see attached photograph MF244884).

    So I would like to ask you the following:
    What is the part number for the bolt on the opposite side of the same bracket?
    It can not be MF244884 according to the catalog.

    Also:
    What is the part number for the smaller bolt on the clamp?
    This is not even shown on the parts diagram as far as I can tell.

    Either the parts catalog is incorrect or the parts can not be purchased separately.
    The bracket and the clamp on my car are definitely original.

    Don't know what to say but my car came with (& uses) two bolts. Maybe the catalog is wrong.

    Do you know if those bolts are original and identical?
    In that case, the catalog is definitely wrong.

    I have 2 Eclipses. One is still unmodified. Both my cars have two bolts, both the same, on this exhaust support bracket.

    Are you certain one bolt is not shorter than the other one?

    I found some good photographs on eBay that show an original downpipe.
    As you can see, there is a difference in length between these bolts.

    This would explain why the parts diagram shows only one bolt (MF244884) at this location and that it is says the quantity required is one per car.
    I believe MF244884 is the longer bolt from what I can tell.
    This means the shorter bolt on the other side of the bracket and the smaller bolt on the clamp is only included with the downpipe.

    Don't take these diagrams too literally, sometimes they don't list the exact full information. Only 1 bolt might be shown on the diagram itself, due to technical drawing reasons, but in reality 2 bolts might actually be used. Also, for simple things such as these bolts, do yourself a favor and just buy some regular bolts from the hardware store. You really don't need to order an exhaust bracket bolt that will probably require shipping from Japan and cost more than 30 standard bolts that will do the same job.

    Just my 2 cents.

    If one bolt is shown on the parts diagram, but two are used, this is usually reflected in the quantity in the corresponding parts list.
    An example is part number MF243660.
    One bolt is shown on the diagram and the corresponding list says the quantity required is six.

    There are three different bolts on the location of the downpipe in question and you would think this means more than one part number.
    I was confused at the start because the parts diagram shows only one bolt.
    However, in this case, it looks like two of the bolts only come with the downpipe itself and can not be purchased separately.
    It explains why only one bolt is shown.

    It would be nice if someone here are able to confirm my suspicion about this.

    I understand where you are coming from, but I only put OEM parts on my car unless something is custom/special like wheels.
    I order parts from Japan all the time and having an extra bolt included does not affect the shipping at all.
    I would not have started this thread if I was interested in buying non-OEM bolts from the hardware store.

    Sorry but I have to ask. You do know Mitsubishi does not make bolts but buys them from a bolt manufacturer??? Same with oil filters BTW. FYI - They all have specs & these things are made to be "interchangeable".

    Am I getting this kind of question because I post in the Newbie Forum?
    Maybe I posted in the wrong section.

    I have used the term OEM several times in this thread.
    Do you think I use a term I do not know what means?

    It seem that way.
    OEM = original equipment manufacturer
    OE= original equipment (genuine mitsubishi)

    I can go buy akebono brake pads for my acura at a local parts store. Akebono manufactures the pads for honda so that makes them the OEM.

    I believe you are using OEM incorrectly throughout your posts. I think you are confusing OEM with genuine as in "Genuine Mitsubishi Replacement Part No. MF244884" being new & coming in the manufacturer's branded & labeled packaging.
    An OE part is an Original Equipment part. It is one that is installed on the car when it is first assembled in the factory. Technically, you cannot buy an OE part as new unless you are getting a new car.

    I know very well what OE and OEM stand for.

    I went through the entire thread trying to understand why you think I am confusing OE with OEM.
    I have only used the term OEM twice and that in the same post.
    The only thing I can think of is that you are confused because I say "I only put OEM parts on my car...".
    That was in context to Kryndon's suggestion about getting bolts from a hardware store.
    Of course I would prefer to use Mitsubishi Motors Genuine Parts as much as possible.
    What I would not do is go buy a bolt from a hardware store that might not be up to Mitsubishi's standards.

    I do not understand why this thread turned into a discussion about OE and OEM.

    get a class 12.9 M10 x 1.25 35mm flange bolt, put a lock washer and a flat washer on it.
    It will be stronger than the one that came on your car.

    or get a MF244884 from mitsubishi

    its the correct bolt

    if you were here in the US i would just send you one of the spare OE bolts i have

    Most certainly not.

    It was used in context to Kryndon's suggestion.
    Maybe you misunderstood because you did not read that post thoroughly enough.

    I always use Mitsubishi Motors Genuine Parts when available.
    Sometimes you might have to resort to OEM parts however.

    Did you see the photographs from eBay in post #7 of an original downpipe with the bolts in place?
    You can clearly see the bolt that is missing on my downpipe is much shorter than the one on the other side of the bracket.
    After looking at the specs of MF244884, I have come to the conclusion that this is the longer bolt that I am not missing.
    It appears the missing bolt only comes with the downpipe like the smaller bolt on the clamp and is not available to purchase separately.

    I do believe the only difference is the length though.
    I am not sure whether or not I will have to cut the bolt for fitment if I purchase MF244884.

    Thank you.
    That is very helpful.
    May I ask where you found this overview?
    It would be nice to know.

    Testosteroni84, listen, we're not trying to argue for nothing here or make you look bad. On the contrary.

    Essentially what you seem to be asking is why these diagrams do not show 100% full, accurate information. None of us can answer that, and even though I'm an Automotive Engineer myself, your best bet is to ask the guy who created CAPS; why he decided to show the diagrams like that and why they don't always list exact quantities and specs (My guesses would be retaining simplicity and ease of reading/navigating). Trust me, I've also had huge trouble finding specific parts using these programs and websites. Not all parts, bolts, washers or even plastic clips are shown here. Some parts also arrive at the factory pre-assembled with existing bolts and nuts, which are all counted as 1 whole part, thus it would be impossible to find each specific part number.

    Additionally, it is very common for parts like these, especially bolts on Mitsubishis, to be used in many models but in different places. The MF244844 bolt (which you're missing) is also used on the 6A13 and 6G72 V6 engines as a tensioner pulley bolt. Some small bolts can also be deemed unnecessary to be listed as a standalone diagram picture and part in these catalogues.

    Trust me, I'd also love to call the guy(s) who built our cars and ask them a ton of questions, but that's simply not possible. But hey, at least DSMPT got you all the correct part numbers and lengths, so at least that will help you...

    So you see now the bolt I am missing is not MF244884 and that the shorter bolt, as well as the smaller one on the clamp, are not shown on the parts diagram included in post #3?

    This suggests those bolts only come with the downpipe and are not offered separately as a replacement part when you are using the parts catalog for this specific car.
    The catalog does not specify that anything is included with the front exhaust pipe (MB906630) however.
    You would have to guess the length (assuming that is the only difference) of the shorter bolt from photographs unless you can physically check a bolt you know is original.
    It would be nice to know with 100% certainty because there is a chance the shorter bolt on the eBay photos is not original, although that seems very unlikely.

    Maybe someone here has a completely original downpipe including those bolts and could confirm whether or not the length of the bolts is in fact different like shown on the eBay photos as well as checking the exact length of the shorter one?

    Kryndon, I never had a problem with your post.

    By the way: Did you notice my previous post?
    Check it out and maybe you see that it is possible the parts diagram is not incorrect here after all.

    The bolt I am missing is not MF244884. It is much shorter.

    No worries. And yes, I did see your last post shortly after writing mine. It is possible that the MF244884 is the longer of the two, as seen in Dusty's picture, although even that one seems longer than it should. HOWEVER, I'm gonna say it again, in this particular case, having it slightly longer or shorter will make absolutely no difference. Not even in terms of clashing with other nearby parts/brackets.

    That said, it appears the shorter of two, the one you're missing, is in fact not shown nor listed in the diagrams. The source that I'm using also doesn't list it anywhere. Which leads me to believe, as I already stated in my previous post, and as you said it yourself, it may simply be a bolt that comes already installed on this exhaust bracket, as one whole part.

    Now, if you want to buy the closest OEM-type bolt possible to the one you need, what you can do is measure the overall thickness of the bracket (with welded nut) as well as the bracket holding the exhaust pipe, then manually look for an M10 bolt with the same length that you get and slap it on there. But personally, I would save myself all the headache and follow Dusty's post #15. :thumb:

    My main concern was that a longer bolt would come in conflict with something.
    It is not possible for me to tell for sure because I am not able to get close enough for an inspection right now.

    This is one of the reasons why I want to get the part numbers.
    You eliminate such potential problems that will cause you a headache at a later point.

    I am pretty certain the bolt I am missing is also used for something else.
    DSMPT provided a list of part numbers and the bolt might be one of them.

    i cropped and enlarged the bolt in that picture. then i measured the pixels of the bolt a few ways and since i know the head is 6mm, i used some 8th grade math to convert it from pixels to mm.

    once i knew that i just dug out a 25mm bolt and tested fit it

    I don't have a stock DP to measure the bracket so i had to guess on how far these bolts went in.
    the small one is 25mm and the large is 35mm. if someone can give me the thickness of the DP part i can get it spot on.

    Out of curiosity why are you being so specific on this? These type of things seem so simple to me yet here we have a 2 page thread about a very inconsequential bolt. This is not a dig. Genuinely curious. Believe me I understand. I've been doing this 27 years and every dsm I've ever owned only had/has mitsu hardware. I wont allow hardware store bolt on my car. Honestly the only reason I dont is because of the metric head size differences. I'm well aware of strength differences where needed. Guess I'm that OCD.
