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.
