You've just got to match the clutch disc to the pressure plate and bolt holes in your existing flywheel. I was a bit skeptical about using the 9-7/8 clutch disc in my 54 truck but it matched up with my pressure plate/flywheel bolt pattern and after 10K highway miles it's as smooth as the day I put it in.
Just a note....the Camaro input shaft has a different spline count than the S10 input shaft and if you're building up a hybrid to run behind a 235, you might have to hunt a little to match up the disc/pressure plate with the correct 235 flywheel.
