What size wheels and tires will fit on a 1970 Dart

I have a 1970 340 Dart Swinger that I have been working on since back in the 1990's (kind of embarrassed to admit that) and I have it Painted(Go Mango) and I am installing a QA1 K frame and upper/ lower control arms and struts and big bolt disc brakes, The rear is an 8 3/4 with 3.23 sure grip and it was changed to big bolt(new axles) and 11x2.5 drums. I'm almost ready to put it on the ground and I was trying to figure out what size wheels and tires will fit under a stock wheel well? I'm leaning towards the Rocket Racing polished aluminum "fuel" style rims and they are available in a variety of 15 inch and 17 inch sizes. I was wondering if anyone had experience running 17's on a dart and what backspacing do you need.
