|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.|

GM Dual Master Cylinr
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.
