Master Cylinder Question

New to the site and haven't figured out the search function. I have a 76 roadster with a 2.8 Chev & T5 and the brake master cylinder is leaking and the booster does not work well. The replacement cost is high and would like to swap to a non-boost system. I have seen where dual system MCs from Fords and GM have been used. Since my car is already a dual line system I can see no reason for a proportioning valve. What is the preferred MC??

Those who use the Ford and Chevy master cylinders usually have bigger brakes. 1" Corvette for example. MGB master is 7/8" with booster. Older non boosted was 3/4". The 78-81 Ford Fairmont aluminum master cylinder is 7/8" (RH outlets) or 76-80 Chevy Monza (LH outlets) and might work. You may have to modify bolt holes and pushrod length. Lines have to be double flare with proper fittings for master.
