Hey, so im putting the motor in tomorrow and wondering if anyone knows of EVERY bolt and nut size ...
i need to know because my buddy took the suspension off and doesnt know where bolts went...


please and thanks!
 
Well i bought 2 m10x75 with the washer, one of them 1.50 pitch the other 1.25 and the 1.25 started but stopped the 1.50 was tight but when wiggling while threading it seemed to thead it 4 or 5 turns with my fingers as to not force anything so my guess is 1.50...but havent hit anything with a wrench yet as i dont want to create a bigger issue but ill try the 1.25 again in a.m always hard figuring out what previous owners did sometimes. Car was missing bolts and had a 6bolt swap with alot of electrical tape and chewing gum haha so trying to get everything as 100% as possible before atempting to drive it other than around the block
 
Not sure if this will help any of the 1G owners. I pulled my entire front and rear subframe. Started going through these diagrams to get part numbers and replace all of my hardware. Since the thread pitch isn't listed I've been testing every bolt individually that I pulled off. I haven't found any bolts that weren't the 1.25 pitch so far. Not saying that's a fact for everything, but seems to be the general pattern.
 
Due to popular demand, I present 1g AWD:

Id hate to start a new thread, so I hope replying to this will work, but do you have that first two diagrams for a 97 GSX? I’m trying to figure out the bolt lengths for the front cross member braces !

If you’re replacing both the bolt and nut, the pitch doesn’t matter so long as the replacements match each other. The original was 1.25mm pitch.
