Hey Whitedog
The vendor that sold me the caliper brackets told me the rotors have part no. of 4886830 which when I was on the NAPA auto parts website came up as a 8 lug rotor. He also told me the the caliper is from a 1982 Chevy K10. The NAPA website has a bunch of rotors under that search. I am super excited about this project.
I also found a company named CPP brakes and they have a power booster / hanging brake pedal assembly for $300.00 and it even comes with the proportioning valve.

I love the ease of working on a brake system when the master cylinder is on the firewall. I can bleed all the brakes all by myself just by cracking the wheel cylinders and or caliper bleeders...
Mechanixman I hope this helps you out...
