Just bought a 1931 model a sedan (5 window) and would like to install power disc brakes on the front. (already have a rear axle with drum brakes for rear) Does anybody know if there is a bolt on kit or any donor parts that will work? And also what master cylinder would work best with this set up. The frame and suspension is all original at this time. This will become a street rod after it is put back together. Thanks for all the help
