Regarding the rearend, since you have a Duster, and A body rears are somewhat expensive you can use a B body rear, 8 3/4 if you can find one. It's a real easy swap, move the perches in 1/2 inch on each side, bolt it in. An 8 1/4 rear would be OK as well, depending on what level you intend to build to in the future.

I put an 8 3/4 B body rear in my Dart Sport and it fit great, I took my time and shopped around until I had all of the pieces. I went through it, installed new 3.55's, a used clutch suregrip, all new bearings and seals for a shade over 600 bucks.

You will need to run a deeper backspace wheel if you run wider wheels ( 5 1/2 in BS on mine 10 inch wide wheel), I did for the first year run factory Rallye wheels and no problems.
