1 1/8" is pretty much standard for 4 wheel power discs, at least for stock style setups.

Cast iron "Corvette" style master. They are available aftermarket through many different companies and performance parts vendors such as Jegs, Summit, Speedwaymotors, etc...Some even now offer them in aluminum.

It works great for me with the 4 wheel disc brakes. I have the early style single piston GM calipers on the front with 12" rotors (b-body spindles), and GM metric calipers in the rear with 11" rotors. And a later model G-body dual diaphragm booster. The pedal feel is perfect......not too hard, not to soft.

If I had it to do over again I would have used a Willwood master or alike.....if nothing else but for the looks of it. I'm not sure if one would out brake the other or not. I can't see it making much of a difference IMHO.

Same exact setup for me. The only difference is my rear discs are Ford SVU/"Explorer" 11" rotors & calipers with parking brake. I got my master, booster & combo valve from Master Power Brakes.
