Thanks for your replies. The wheels are identical, and both fenders are original. I did in fact find the problem. I took the new beam out and did some measurements. It turns out, that the beam is actually welded together incorrectly. It seems as though one shock tower is out 1/8 inch at the bottom, and continued to move further outwards. I also found that the torsion bar tubes were different lengths as well. I put the original beam back in with the CB drop spindles, and everything lined up perfectly.
