Looking for a Budget Master Cylinder with a diameter below 1' for my Scarebird Disc Brake Swap on 68 Belvedere Station. No need for the 100 bucks aluminium 15/16 MC from Mopar. Did Mopar put any that small Diamater MC's in cast iron? I used the 1,xx from a 76 Cordoba in another application but with power brakes. For this project I want to keep the brakes manual. Wilwood makes some very cheap 7/8 for example but can I get adapterplates to mount them properly?
