Rear bumper brackets needed

[Bearcuda]

Hey, not sure if I posted this previously or not. I'm looking for 70-72 rear bumper brackets for my 73 Cuda. I'm trying to move my rear bumper closer to body and get rid of that ugly filler piece. Anyone have any spares?

Unfortunately, I have the earlier Challenger rear brackets. But do you have the corresponding year rear bumper to go with the early brackets? I believe you may need it because of different attachment points. (Somebody please correct me if I'm wrong & I'll know for sure.)

It's weird cuz whoever I bought the car from put a different year bumper on it because there's no spot where the ugly bumperettes used to be. But, it's still the factory distance from the body with that middle filler piece between the bumper and body..
