Looks like the main housings are the same for 50 to 51 later rear assys. I have taken them down to where the backing plates look like they will swap. Housing measurements appear basically the same and the 51 the plates unbolt where the 50 has rivets that will drill and be replaced with bolts. The patterns for bolts/rivets appear the same. Anyone ever change these? I also could use at least one new axle and a new set of spider
gears are any of this available anymore?? I need any help for information I can get...thks for any help..
