I was thinking about buying the one from member rick ehrenburg he has new mopar master cylinder for $73 shipped.i just dont know which one to get,like the bore size etc etc? Or can i use my stock manual master cylinder? also do i need a proportioning valve? If anyone give me infor can you give me a part number on a master cylinder i should get? im running wilwood brakes i dont think they would make a difference

With 4 wheel disc you are most likely going to need the big bore but that is dependent on the piston sizes in the calipers and pedal ratio.... if you go to a large bore and it isnt needed you will have a pedal that doesnt move much and would be rock hard

Sounds like you still have air in the lines... are you using braided line all the way? If so, thats part of it
