Thanks for all the advice. I called Stockton Wheels they have the LBP 15" rallies with the corrected backspacing for under $150. I think I'll go that direction.
Thanks again
I am looking to replace my '70 dart 7.25 with a '73 8.25. The 8.25 is 1.8 inches narrower. I am not tubbing the car or relocating the springs. Will .9" spacers work or is there another way.
