I am doing a 1.5in notch in my frame and using the stock sized ford 9in rear end not having it notched at all. From your experiences what is the largest tire that I can fit without have to roll the lip or do tubs?

I think the tallest tire people are running on there G-bodys is a 275/60/15. Not sure what back spacing though. Doug

275/65r15 will fit on an 8in wheel with 3.75 or 4in back spacing.

You'll have about a 1/2in on the frame and 3/8 from the lip.
