Hey guys I have heard of people switching their ford I-beam axles over to disc brakes using junkyard parts. I hear that it is dodge discs and gm calipers. My question is has anyone done this swap? If anyone has what year axles does it work on? What discs and calipers are used? What bearings and seals do you use? Any input would be helpful because as with alot of people these days money is tight. Also I know speedway makes a nice conversion kit for my '37 axle but I was hoping to do it cheaper.
