Anybody running 17" Cobra Bullit rims on a Duster

As mentioned in the link above, these wheels should fit better(w/o an adapter/spacer) in the rear with a b-body 8 3/4. I have a '67 dart, and have found a cheap set of 17x8 factory Mustang GT (bullitt style) wheels. I've been toying with the idea of swapping out my 8 1/4 non-posi rear in favor of running a wider width posi. 8 3/4 rear, and relocating the spring pads.

Thoughts?...


also... I'll be running a 5.7L out of a 300c.
