Very few wheels will fit. Get spindles off a '94-'95 Mustang (v6 or gt or cobra) and get the calipers too (better brakes).
Then get two used driver's side axles from a '92 or older Ranger with a 7.5" rearend. They should be less than $50 each (I paid $80 for two, the cheapest price around here). Then get Ranger drums and use your stock rear brakes.
Thats the conversion Im doing. Im just waiting for the spindles and calipers I bought to get here.
Im using '03 Mustang V6 wheels.
