68NovaSS After market MC's come in several bore diameters, 1.25, 1.125, 1.031, 1.00, etc. In my Nova I used the early Corvette dual MC with 1.25 bores for discs all around, GM fronts, Caddy's rear with a GM style proportioning valve.. Keep in mind there are two different length push rods in the mix as well.

Can anyone tell me if the bore size on the 70's GM type master cylinder. I want to install a dual setup on the 32 and if the front and rear are the same I can simply line up the brake lines in the reverse as the master cylinder will be installed backwards under the floor of the car. I am running disc on the front and drum on the rear and I already have the residual valves in place. Thanks for any help. Master cylinder casting number is (I think) 5460346. I tried checking up on bore sizes and came up with 1 1/8" but I want to make sure that they are the same for front and rear.
