Cuda bumper bracket swap, which brackets are which?

[73cudakid]

I am swapping my 73 bumper guards to the 70-72 style. I have both sets, but cant remember which are which, since its been so long. I want to say its the longer one since the ones that came off the car (shorter ones) were extremely pitted.
Thanks

here are the 70-72 rear cuda brackets, what stamp number are on your brackets?

The one set has no parts numbers and the other set is 2962307-L&R, 46570-A. I believe those are the 70-72s but just wanted to make sure.
Thanks

First . . are we talking front or rear??   Either way . . the smaller ones go for the 70-71 usually.

Rears. I believe that the shorter ones are correct as well. The previous owner must have had the 70-72 brackets already on the car.
