Brake

Joe, when I bought my 1962 Starfire the previous owner had installed a brake booster, dual master cylinder and a proportioning valve along with 4 wheel drum brakes. He also removed the 394 and slim Jim and installed a Chevy 350 and th350 transmission. He welded the engine mounts to the front member and the trans mount was attached to a 1/2 inch piece of plate steel attached to the frame rails.
I know that early cars didn't have prop valves, but you never know what people will do, that's whyI asked the question and I along with other people that I've talked to are tired of your critical and sometimes smartass replies.

Had you told us in the first post that the car had a non-original dual circuit M/C, you would have gotten a useful answer a lot sooner. The mind reading thing still isn't working, so one can only assume the car is original unless we're told otherwise. As others have noted, the original single circuit M/C used a 1/4" line from the M/C to the splitter block. From that block, three 3/16" lines went out - one to each front wheel and one to the rear axle. When GM went to a dual master cylinder, the line to the rear axle was bumped up to 1/4". The reality is, either 3/16" or 1/4" will be fine. The drum brakes don't use enough fluid for the line diameter to matter. Many other manufacturers retained the 3/16" line to the rear even with dual M/C and front disc brakes. It just isn't that critical to the function of the brakes.

I've done a few conversions to dual master on the 63 and 64 full size. I replace the rear line with 3/16 right to the master cylinder and I replace the 1/4 to the spliter block with 3/16 and plug the rear line that would go to the rear wheels.
I've had to play with the plunger length changing from single to dual but once it works it stops better then with a single master.
