LCA disassembly??

[XtechX]

I have used the control arms off from another truck that had been basically all redone. But when I put them on my truck, the left one worked fine, bolted right up tight. The right one went on but the u bolt on the front of the lca wouldnt seat correctly, the rear one was fine. It seems that the po of the donor truck put the lca cross shaft in backwards. The rivit wasnt in the divit.
So this is my question if any of my ramblings made any sense. First, if I leave it like that will it be difficult to align or most important of all, be safe? It's about an 1/8" from seating correctly in the u bolt saddle. Also, how do I disassemble that shaft to turn it around the correct way. If I do that, do I need a new one? Any pics, showing how to get them apart would be great.
