For those that have a CPP, firewall mount, disc/disc master cylinder, what is the real world application/replacement for the master cylinder? Would I be correct in assuming something Corvette? I bought his thing back in 2006 or so? Should be CPP part #4753FBB4.

Why not call CPP?? Oh, you know. The usual internet chat of how difficult they are, multiple problems with their product, etc., etc.
