Ford 8 inch rearend swap

Dont waste your time or money, get a early b body rearend 1962-1963( 58-1/2) move the perches in, bolt in the early a body and get 1.25 off set rims and your ready to rock, did this to a 66 dart.
That's fine if you can find one. Two year, one body style only. How many do you think are still out there?
