jim i rebuilt the old master, the bore in it was a little rough
but for now it seems to work fine. and stops good of course i have
no bed and no extra weight. i think that they would do for a show truck i will add the hydrovac later as i want to haul my old tractors on it. the single unit master and booster wont work on a 46 with the existing brake pedal and theres not room for it any way. so im going back with the orig. set up
