Thanks Yellow52. I have the bed wood in there, and one of the fenders on, and the bumper, but still, there's a 2" diff between front and rear of the running board. Also, The fender seems to be riding about 6" above the wheel. Granted, I don't have a cab on yet, but that should impact front and back equally, and front sheet metal might even make it look worse. I'll wait until I get the truck all together, but just seeing what I am up against.
