Rear end location wrong? IM STUMPED!!!

I have a 70 dodge dart swing that I'm in the process of converting to a BIG block. I've installed (Hotchkis- a-body Geometry Corrected leaf springs) with the 1" lowering into the car. Has disk brakes in rear from SSBC-USA. Didn't change any thing other then the leaf springs. Got everything bolted up and now the issue. My Left rear tire is about 1/16" from fender lip and right rear tire is about 3/4" from fender lip. Tire size is p245/60r14. I Loosened up everything took the weight off the leaf spring and moved the spring shackle hanger on driver side inward a bit and passenger side outward a bit and tightened everything back up and only gained about a 1/16" on both sides.
Does anyone on here have any ideas to what might be the issue?
Also, the springs I took out were factory and didn't have any tire clearance issues!

Thanks in advance
