Dual Pot Master Cylinder Conversion 65 Dart

The newer aluminum master cylinders are a 2 bolt design, and AR Engineering makes a very nice adapter to mount them to the firewall. There are 2 types, because A bodies have 4 studs sticking out of the firewall, while B & E bodies have 4 holes where bolts go through with nuts inside at the pedal assembly. Cass (Dr Diff) sells them as a kit, and he's the only place I found to get the 15/16" master for manual brakes.
