Tire Size 68 Barracuda

I have to have more bs. I only have 3 7/8 to fender lip but 7 1/8 to leaf spring. That’s because of the b body 8 3/4.

Yeah that sounds about right, and the 5.68” of backspace should place that wheel pretty well. If you really wanted to max it out for tire width I’d say you’d probably want to be at 6” or maybe even a smidge more.
