Weld wheel backspacing for Dart front wheels

These are the ralley's on my sons Dart. The body is all stock. No tubbing and no springs moved in. The back are 15 x 6.5 with a 4.5 back spacing and a 245/60-15 tire. It fits with room to spare. The front are stock 14 x 5 but to be honest I dont remember the back spacing. :scratch: If you really need it I can check tomorrow. Ron
