Ford Exploder 8.8 rear axle....

My brother-in-laws brothers son has a 71 swinger, 360 auto with a Ford rear end under it, been sitting in the back of the shop ever since I can remember, dusty with stuff stacked on it, pitiful looking green thang. He said he couldn't keep an Mopar rear under it, He's pretty sharp on stuff and is a pro mechanic at his Dad's shop, I could call get get some specifics if need be.
