I was surprised that the metal gauge was the same on both. The Goodmark passenger side has the wrong marker light cutout for a '72 to '76 (as advertised). Did they not have or weren't able to supply the correct stamping for the later years? Are the body lines as crisp on both or is one better? Thanks for you effort in reporting this info.
As was I. Everyone always reported the Goodmarks were thinner. Which they are. But they're still 18 gauge. The AMD it appears is closer to that 16/17 gauge. Measured in multiple spots on both.
As for the cut outs, the AMD is also in the wrong place, so since I'm gonna have to modifying that anyway, I didn't hold t against either panel. In both advertisements, it said the marker light cutout may have to be modified depending on year. So didn't hold that against either panel as well.
The bodylines on both are equal to the naked eye at least. Smooth, crisp and pronounced. I don't see any spot other than the noted figment issues that vary between the panels or what's left of the originals on the car.
