Thought I would share a little info with other 71 Charger owners that may need quarter panels. I just completed the installation of and AMD quarter skin on this 71. 72 would be the same situation. On this car, I elected to use an AMD quarter skin, rather than a full quarter. Reason being, I didn't want to disturb the lead at the roof seam, or remove the back glass etc, plus the upper was all good, so I decided to leave as much original intact and undisturbed. I used a new AMD trunk extension and reinforcement bracket as well. These panels are heavy gauge metal, just like original. They have the same flanges and dimensions as the originals too. I butt welded the new panel in place and metal finished the weld joint. No body filler required. The fit of this panel was excellent. The door gap, rear valance, quarter extension and wheelhouse fit was spot on. I cut the new panel 1 1/2 inches below the body line to keep the factory body line in place. I will re-lead the rocker joint as the factory did. I could not be happier with the fit and quality of the panel. The marker light opening is accurate, and the flanges have crisp bends just like the original panel. hats off to Auto Metal Direct for these awesome parts for our 71-72 Chargers!
