if im not mistaken, the all pro hanger can be welded on two ways, one moving the front hanger forward, one being the stock location. Maybe that could be part of the problem. How is the wheel position in the fender?
this is your problem. TO THE FLOOR and i did the all pro hanger swap on our buddies 81. the hanger goes two ways. i bet thats also why your shackle angle came out so far. from the pics it doesnt look like your axle moved that far farward either. so im going with that hanger is on backwards(stock location)
