89 TPI Parts on an Older Base
Will the rest of the stock 89 TPI components bolt-on to an earlier base without issues? I'm considering a ZZ4 and I'd like to use an older GM base with the rest of my stock 89 components for now. 
Thanks.
Thanks.

yes it will work. the vette has a slightly differant base though! so any f-body 85-86 should work.

I have no idea. My friend that sold me the TPI took it to work and bead blasted it at his shop to make it nice and purty.
