I recently purchased a 1967 Polara 500 Convertible with the Budd disc brakes. I am going to change to the 1973 front disc brakes over the winter. I will be using a 1973 master cylinder and proportioning valve. What size (cylinder bore diameter) rear wheel cylinder should I get?
I see that the rear wheel cylinder dia. with front drums for 1967 is larger than for front discs. But the rear cylinder diameter for 1973 (front disc only ) is also larger than the 1967 with disc specs. Thanks
