Where do these gaskets go?

Thanks. I saw that. They're definitely for the rear bumper brackets. It's just weird that only two of the 6 bumper bracket bolts actually enter the interior of the car, which would warrant a seal (on a '66 Dart at least). Maybe the rear bumpers on other early A's have all 6 enter the interior.
Does your Dart have the corner/side brackets or maybe for the bumperetts
