I need a small master cylinder with 7/8" bore

Ditto w/ the after-market Holley 2-D Pro-jection TBI kit I put on my 65 Newport in 1996 at $600 retail price. I never realized improved mileage or performance over the carburetor and it had many quirks that I never worked out, mainly from a bad fuel controls concept (no MAP or MAF sensor). Many people find it better to retro-mod w/ factory parts. In front brakes, those are advantages of using the 1973+ A-body setup (spindles, hub-rotor, calipers) or Scarebird's kit (custom mounting plate w/ GM caliper & Toyota rotor).

Yup, I've been involved with the automotive hobby for 40 years and have worked at three different performance/racing parts manufacturers. Nothing beats OEM parts for quality and fit. I had considered using a factory front disc setup. The only reason I did not was because I don't like the wider track width they have on A bodies. My brother is currently building a 71 Dart Swinger. It was a /6 car with the same puny drum brakes mine had. He purchased a front disc setup from a vendor off ebay. It uses Toyota rotors and GM single piston calipers. All the kit is, is bearings that enable the Toyota rotors to mate to the original spindles and brackets that mount the calipers. He purchased the rotors and calipers from Rockauto. I forget how much he spent but I do know it was far less expensive than the $600 I spent for the setup on the front of mine. It will be interesting to see how well they perform. He's using factory 11 inch drum brakes in the rear.
