So in order to run a 28x10.50 M/T Slick with a stock width 12-bolt and stock ride height rear spring I'll need to run a 15x8 w/ 5" or 5.5"bs?

If the 12-bolt is the same width as your stock rear end, then max of 4" backspacing will work without frame problems. If the 12-bolt rear end is stock length for '68-'72 chevelle and/or monte then 5" backspacing will work. Some of the guys on here have mentioned using 5.5" backspacing wheels but I don't see how without a frame notch to the seem.

Thanks, it will be a stock length A-body rear. I just wanted to make sure the 28x10.5 will tuck and NOT rub with a 15x8 w/5"bs on the stock width A-body 12-bolt.

Thanks Again
