Narrowed 8.25 Rear in 72 Dart?

Hello all,

This is my first post/thread here on For A Bodies Only, so hopefully you can help me out. I have a few questions about swapping a narrowed 8.25 rear end with a Sure Grip diff and 3.91 gears in my 72 Dart.

The rear has been shortened by 4 inches on each side, so I'm a bit worried about clearance issues with the inner fenderwell. I wanted to know if I could get away with not mini-tubbing the fenders if I had the proper backspacing for my rims and the leaf spring relocation kit (I'm thinking the smallest amount of spacing I can safely get away with). I will most likely be using some stock large bolt pattern steelies stretched to 8 inches wide with a 245/65/R14 tire.

Also, the guy has a 727 trans in the Valiant, and I wanted to know if the 8.25 slip yoke for the 727 has the smaller 7260 U joint like my 7.25 I have now.


Any help is greatly appreciated,
