So I got all that finished and I hit my second roadblock. I need to know the size of bolts needed to attach the clutch pressure plate to the flywheel. On the flywheel there are both 3/8'' and 5/16'' threaded bolt holes, and on the actual clutch pressure plate assembly there are holes just over 3/8'', so you would assume to use the 3/8'' bolts. In my instructions it says not to use a bolt with a head larger than 1/2'' (which would be a 5/16'' bolt) and then the gm dealership says to use a 5/16'' x 5/8'' bolt which is nowhere near long enough because the threads on the 5/16 holes on the flywheel dont start until the middle of the hole. so im just lost. heres some pics for clarification what should I use?
