I got an AMD rear valance for my '72 Challenger. It looks good and I have not fit it to the car yet as it is still on the rotisserie. I have filled in the bumperete cutouts and while I was doing so I noticed the license plate holder out of level by over 3/8". I drilled out the spot welds and realigned and welded it in place. Hopefully when I get the car back on it's wheels and can fit the part it will have no issues. Hopefully that can take place in the next month.
