1970 Duster base model slant 6 rear differential 2070051 spider kit

A new cut to fit Ford 9"rear end w/driveshaft is over $3000 or more now & she just can't afford that right now. Joel
Just a FYI:
A 8 inch Ford rear from a early Mustang, Comet, and some others, with the (V-8) 5 on 4.5 bolt circle, is a 90 percent bolt in swap. Don't even need to change the drive shaft, just a conversion U-Joint, or (what I would do) have the Ford "ears" put on the Mopar drive shaft. Then just use a stock Ford U-joint.
