I'm in the same dilemma. I have a 67 Dart GT. Will be putting in a 400/ 727 next year. Installed an 8 3/4 already and plan to go with 10 x 2 1/2" Rear Brakes once I order Dr Diff Axles. I have all the front end braking stuff, 10.95" Rotors, Single Piston Calipers, etc with 75 Scamp Spindles & Adapters. Also have a Standard Disc/ Drum Proportioning Valve as well. It will be a Manual Disc/ Drum setup, but trying to figure out what Master Cylinder would work best for me. I'm thinking along the lines of at least a 1" bore (give or take) Kind of a Happy Medium between Soft Pedal or a Hard Pedal. I do want to be able to stop given we all have a lot of stupid people out there on the road these days. Anyone have a suggestion? Kinda leaning towards the Aluminum 80's type M/C's Just need to know what Model of car used a 1" bore size. So far I am leaning towards the 15/16" from mid 80's Diplomats, 5th Ave. (As suggested by Cass (Dr. Diff) But I am cheap (actually just a poor dude) lol and need a Part number so I can order it from Lordco. I am in Canada. And have no access to the US market.
