Anyone have pics of 1974-1975 bumper without bumperettes removed?
Any of the later bumpers with the big rubber bumperettes should just have a couple of mounting holes behind the bumperette that can be filled with a carriage bolt. I know the bumper is a little different on a Duster, but on mine the bottom bumperette hole served double duty, it was also the lower bumper bracket mounting hole. The upper hole was just for the bumperette and was larger and round. But a carriage bolt could still be used to fill it, it would just take grabbing the square shoulder or double nutting the bolt from behind to tighten it.
Here's a '74 Dart bumper in stock form. Sorry, I never took the bumperettes off this one as it was a parts car I basically bought for the '73+ brakes and V8 K-frame. It had been clobbered in the back and didn't look bad, but the rear rails were folded up and wrinkled all the way to the spring mounts.
