Front case/Oil Pump Differences

[spyderdrifter]

I don't have any way to check this first hand, and don't trust websites that show pictures of something other than the specific part. I'm looking to see if an Evo 7-9 front case is able to properly bolt to a 6 bolt or DSM 7 bolt. I have an idea in mind, but need to know this before progressing.

I don't know about the EVO part, but 6 and 7 bolt front case covers are not an exact match..

Right, I know those two don't match. My guess is an Evo one wouldn't match a 6 bolt either since it's a 7 bolt as well.

It wont work. Alternator bracket mount is in a different location between the two.

I noticed that too, but I may not have an issue with that part. I did notice the differences in hole placement on the case gaskets as well. Does anyone know how well those may line up with a DSM 7 bolt?
