66 Barracuda ?

Hey guys and gals, I hope you all can help me determine what is correct for my wife's car. We have it at the body shop ready for paint, but on the rear quarters by the taillights, are these dimples in the panels. The left side looks like it was stamped like that, but the right side had previous damage so it's hard to tell. Anybody ever seen these dimples? Every other 66 as far as I can remember didn't, but I want to be sure. My body guy isn't too sure, because he hasn't really messed with early A's. Thanks in advance. Neil
