I recently installed a front disc brake kit from speedway motors in my '53 3100. It is a nice kit, comes with roller bearings, rotors, calipers & brackets, brake lines, pads, and all necessary hardware and spacers for about $250 plus shipping. The instructions could use a little improvement, but it's a relatively straightforward setup. Overall I'm very happy with this kit, unlike some other items I've gotten from them.
