Front Rubbing - Tires, Suspension or Wheels?

Here is the situation in the rear. This is a shot of the driver side:



Here is the best shot of the inside edge I could get (that's a small wire brush):



There is even less clearance on the inside of the passenger side (not a whole lot, but I couldn't get the brush in there vertically).





Because of how my exhaust is routed, the 295s are barely rubbing there as well in the corners.

I found a measurement of 57 1/8" for drum to drum on the 8.75 and mine appears to be just under that. I just hate to spend $740 on two wheels just to have to run spacers. I found that I have Mopar Performance Competition leaf springs (are these what everyone refers to as SS springs?) so I definitely want something lower and that worries me too with rubbing.

You mentioned long enough studs; this is what's on there currently:



I'll need to swap those out as well.
