I know this has probably been beaten into the ground and I even searched the archives but could find the exact answer, so here goes. What is involved? Does it take a new axle or is there just a spacer? Also, can the fenders just be taken off or are they connected to the bed forever? Could you just cut them out and weld a new panel in?? I found a 1st gen truck but its a dually and I cant hack a dually beings Im a young driver. Thanks
