66 Dart master cylinder replacement

Well I was starting to question my sanity during this brake job. . . The Reman Napa 68 dart MC i was using was bad. it was weird, i bench bled it and bled the brakes so many times went through 3 or 4 BIG bottles of fluid. It kept sucking air into the MC, no leaks but it must have been a bad MC. I said screw it and bough this:

Its MUCH better now! Got the adapter plate for a 2 bolt MC and the 10psi residual pressure valves from mancini's also. I'll get some pics soon. Everything went together perfectly and only had to do about 4 or 5 cycles of "pump pump pump pump pump, hold . . . bleed" on each wheel. Now its got a super solid peddle. Those residual pressure valves make it really nice too, it keeps the springs from pulling the shoes all back in so the peddle travel isnt far at all, its "right there" and she stops like a champ. Highly recommend this set up.
