I just bought an L88 flywheel which supposedly uses a 10.5" clutch. I thought Chevy's used a 10.4" clutch, not 10.5". I am aware that there are other clutch diameters for Chevy's. I am buying a 10.5" clutch with a 14 spline count from Advance Adaptors, but I still need to buy a pressure plate. My question is, can a use a 10.4" pressure plate, which seems to be a lot more popular and inexpensive versus a 10.5", or do I absolutely need to use a 10.5" pressure plate?

My old L-88 flywheel used a 10.4" clutch just fine, probably because that's what GM used on them in the first place. It was too light for my setup (M-20 & 3.08's in a 3000# Nova) so I went back to the stocker, but the clutch fit and worked fine.
