73 challenger bumper

[cudarudy]

I have a 73 challenger that I want to replace front bumper , remove filler panels and move bumper in. Do I need 72 bumper and brackets?. The rear bumper is good condition just want to move onward. Do I need 72 bumper brackets?

The easiest way is to use 70-72 brackets and ideally 72 bumpers, as the 72 bumpers have the slots for the jack. But there are other ways that will get you there as well-
