73 to 70 rear bumper swap

[1973challenger]

Good morning forums!

I’m currently working on a 73 Challenger. The rear bumper had been damaged at some point in the cars life so I wanted to replace it. The plan is to swap the factory rear bumper with the 1970 bumper.

Here’s my roadblock. The factory bumper I own has an inner support bracket(correct term?). This is also bent along with the bumper itself. I just received the 70 bumper and 70 rear brackets yesterday. From my google results I am having trouble finding any solid answer. Is the inner support bracket from a 73 compatible with the 70 style bumper? If not, does anyone know of a source to find reproductions?

Thanks for your time!

It is not compatible. 70 does not use the inner reinforcement.
