FYI replacement drivers side lower fender tab pop rivet in place with adhesive .exterior pop rivet should be low key when painted.. Pearl 78 / 455 X

Ah, this is just below the headlight bezel on the ends of the valance? I had to do a repair there myself. I hid some rivets below the headlight bezel as a temporary measure. Eventually I'll just rebuild that flange with some fiberglass, but I just wanted it together. So I used some wire to pull the two sides together after riveting a bracket onto the headlight bucket. Nothing visible from the outside, but an obvious hack job from inside the grill area. Hopefully I can straighten it out someday soon. It's definitely not the best aspect of our body design--a bit of a weak spot for sure.
