Bob, I know nothing about 300Ks. I have an H, BUT I do know that Booster Dewey at Power Brake exchange in Portland does a really great job with boosters. He has done all my boostrs over the years. My H, like all H's, is supposed to have a dual diaphragm booster. NAPA sells a single diaphragm booster which doesn't work very well, although the car eventually stops. Dewey noticed it was a single diaphragm and asked me about it etc. It made a terrific difference. I think a lot of H's have the wrong booster judging by the pictures I see.\ I would give Booster Dewey a call. He may know a source for master cylinders, although my NAPA master worked just fine after I adjusted the pushrod the shop manual says not to adjust! http://boosterdeweyexchange.com/ 503-238-8882 Good Luck!
