I have seen a few pictures of K 64 1/2 and early 65 cars with a Power brake booster with a standard master cylinder.
Since disc brakes were not available in 64 or early 65 AND the power brake option was only available on auto trannys (according to the research that I have found) what is the correct brake set up?
Also can a power booster be used with a clutch? Assuming you don't have disc brakes.
