Will 15 X 10 wheels fit the rear?

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.

I'm guessing now that I could go with a 8.5 wheel and then determine the backspacing on it. And also go ahead and get the offset hanger kit that only moves the leaf in about a 1" or so. I will however install the kit first then do the measuring. I know that a 275/60/15 tire recommends I think 9 to a 10 inch wheel but not really sure on that. Here are some pics with the stock wheels and 235/70/15. Using a tire calculator the 275/60/15 are a shade bigger far as tire diameter not width. I will check that out later.
