12:05 Garage- ’70 Duster build

Hi, I was wondering what backspace you used on the rear. Also just to confirm, you did the leafspring offset and not the relocation.

I have a 63 Dart mini tubbed and would rather not do the relocate. But unsure if my 295/35r18 with 5.25b.s will fit with just the offset hangers. My wheel well lips have also been trimmed.

Thanks.

The rear wheels are 6" backspace, and yes, only offset leaf spring hangers. I also have stock width 8-3/4 and Cobra style discs. I also trimmed about 3/8-1/2" off the wheel lip. It's crazy how wide the factory lip is on these cars.
I've never messed with the early A-Bodies, but I have to bet backspacing requirements are no where near what a Duster body will take. My suggestion it to make you own measurements about 10 times to make sure. I used a carpenter's square to take all the measurements, then started my search online for off the shelf wheels that would work. Most tire manufacturers have their tire dimensions on their websites.
