This is what I was thinking of:
Clutch Master Cylinder Mounting
This is the camaro TOB in the bellhousing. I have a thick spacer that summit sells plus some other thin spacer. Don't remember all of it off the top of my head. The throwout bearing itself without the fittings is about $50. The fittings are probably under $15 ea, and the spacer kits, well, I don't remember but probably under $100 total. Then you need the hoses and a remote bleeder kit if you want one. Though you could probably use the camaro one if you wanted to.
