8.8 Explorer rear in early A body?

Mustang 8.8 has the correct width (same short axle both sides) Just put Mopar perches on it. Get Spicer 1350 bolt on flange or graft Ford joint end on your driveshaft. Dont know why you want disk out back, but the Ford LS is cheap. The long side is about 3" longer than the short, thats how much you have to section out.
