I am trying to go with a larger rear wheel and tire on my 1970 Barracuda. I have a Dana 60 (Strange S60) with the B Body Brackets and off set rear springs. I was planning on using Vintiques Rally wheels 15 x 10 with a 5.5 inch offset. Currently I have a 15 x 8 with a 4.5 offset. I got the wheels but the fitment looks wrong (fender side)....
