Guys who are Mini-Tubbed please read...

I used a B body housing and narrowed it 3.75" on each side.
Mini tub and a home brewed triangulated 4 link. 15x10 with 5.5 back space and 325/50/15 MT Streets puts it dead center on my 67 Dart. I did not roll the fender lip
at all and I got 15" in the clear after mini tub.

Since you are spending alot of $$ you should shorten the housing in my opinion. Will look funky with too much backspace.
