Don't fit out of the box. Disappointed. Had to grind down all 8 mounting studs to a smaller O.D. to fit the Ford doors properly. Typical aftermarket poor quality fit. For a commercial shop it's a no go. Too many hours to make it fit, and the customer won't want to pay the extra hours it takes to make the aftermarket parts fit.Also, the marker and signal lights were reversed from side to side, so the marker was the top one on on side, and bottom one on the opposite side. Looks stupid. I had to remove one lens and reverse the bulb sockets to correct. Again, not impossible to fix, but more time that shouldn't be necessary for installer to do.If the mfg would correct this, then it would be a great upgrade to the '99-'07 generation pickup. Seems to be fairly good about not vibrating, etc.
