One of my 69 Darts has 15X10 inch wheels on the rear they have a 7 1/2 " back spacing ,the car also has a ladderbar setup and is mini tubbed.I don't see how a 15 X10 " wheel will fit on a stock spring location. My other dart has the springs moved inboard and has stock tubs and I don't think a 10" wheel will fit it.I could be wrong but it sure don't look like it will fit.
