Re: 57 Short Box 235 5sp C4

One of the things I wanted to figure out before I mounted the cab was the brake master cylinder. Original plan was for a vacume boost master to operate the C4 brakes. I wanted to use the original pedal and after looking at several 7-8" boosters advertised as useing the original pedal, i was haveing trouble convincing myself the small booster with the limited vacume of my 235 would end in a happy situation. i decided a hydroboost system would be the best alternative. More research, reading, help from members here and a few trips to a couple of junk yards I came up with a mustang cobra hydroboost as one that should work. I wanted a remote reservoir and the plastic one it came with would come off pretty easy. I needed to make some fittings to accept lines from the master to the reservoir. A little measureing and lathe work I came up with these.
