12:05 Garage- ’70 Duster build

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.


That’s great, I appreciate the info. You’re rear brake kit.....is it by chance Dr. diff kit?
