1973-74 Bumpers.

If u took that off would it work on a 73 duster ? Or would they be more holes than u need?
You can make a set of mounts to adapt the ‘74 bumper to the’73 from a couple of pieces of flat stock and some 2” square tube, I made some for my car I will see if can get you a couple pictures later today. Its bolted on the car currently.
