I read the post, but looks like everybody is using their stock rearends. The dana 60 I want to use is from a early b-body which is about 2.5in shorter than the stock one. I was figuring with the narrow width and Dr Diff kit that it could get possibly get 15X10 or 15X12 rear wheels back there and still have pleanty space for driving and tire exspansion. Since neither of my cars are here to do any measuring, I don't have a way to check the spacing for a few weeks. I'm trying to find some vintage slot mags for the fit, and hope that someone already did the work and could shed some light on it. Hopefully I can find a nice pair of rims by the time the car is here and ready to work on.



Thanks everyone for your help on the info.
