92 Corvette clutch replacement
I recently purchased a 92 Corvette with a bad clutch. I already have it tore out and the new clutch kit setting there but I had to turn .060 off of the flywheel to straighten it out. My question is do I need to have a shim to make up that space and if so where do I get one and what size shim will I need? Thanks

I surely hope you didn't turn the dual mass fly wheel down. If you did, get another one. They are not made to be turned at all.

I'm with Strick on this: the dual mass flywheel can be "faced" ~ 6 thousandths max - but turning it down 60 thousandths doesn't lead to anything good.
If the price of a dual mass replacement scares you, then yes there are flywheel shims available. You'll have to look for them, a lot of parts supply houses don't know they exist. I think that I have gotten them in the past from specialty clutch supply houses rather than any regular parts store.
if you assemble it without replacing the dual mass flywheel or getting a spacer then you are likely to have a dragging clutch when shifting. A dragging clutch will quickly damage a ZF trans.

Just to give an update I made my own .060 spacer and put it back together and have been driving it without any issues. It works fine under normal driving and hard acceleration. I can definitely see the issues it would cause without it and is why I asked where to get a shim. I searched very little before I decided to make one.
