There is so much info out there, I dont know what to believe, One guy says 15x10 with 7.75 B.S will fit under a stock 1970 Dart, others say 15x8 with 4.00 B.S. People are all over the place with this. My ride has a 8 3/4 rear with 10 inch drums. I know someone has done this. I cant be the alone. I just want a little meat out back without cutting my ride up. Thanks in advance.
