I just picked up a 59 stepside. Sitting for 20yrs so brakes are shot. All original except metal floor in bed. 292 3spd. I would like to upgrade & have found some part info on disc brake conversion. I dont want to buy a kit! I have even tossed around the idea of converting to 4wd. What I havent found (limited internet time) is what power master cylinder will bolt in. I thought one day I read that there was one that was a direct bolt in but cannot find the post now. Someone suggested a ranger m/c. Can anyone help me out? Please :-)
