72-73 bumper brackets & bolts
I dug out a set of 72 brackets, (top), and a set of 73 brackets, (bottom).
They are placed in the positions that they are mounted on the car.
The difference of about 1/2'' in length is apparent, and on the end brackets the hole spacing is offset more to move the 73 bumper further away from the body.
Pictured also are the bolts, from the 72 set, need 10 of each. The stainless capped 3/8'' thread bumper bolts have a 3/4'' diameter head, 3/4'' long under the head, and the nut has a 1'' washer attached. The 3/8'' thread body bolts have a 1 1/8'' washer and are 1'' long under the washer.
The last picture shows a rubber strip that goes on the sheet metal support that is welded to the rear body panel under the filler neck hole. I'm not sure if all years have this, or just 73's, to take up the extra space between the bumper and the body piece. I've only come across one on the cars I've had, a 73.
