Is the picture you show of the 72 bumper you have? If so, it must have been modified. The original bumper for a 72 does not have a stud with a round rubber spacer on the end. It has a bracket with a captive nut and you attach a bolt from the inside of the fender to secure it. There is a thick rubber square with a slit in it that covers the end of the bracket with the nut to protect the paint on the car. I happen to have my front bumper off my 72 now, so I can take a picture and post it tonight if you want.

Yes, the bumper on the picture is the one that was sold to me as being a 72. Does the bracket to which the stud with a round rubber spacer is attach looks like the bracket on your bumper ? If so, how about i remove the stud with a round rubber spacer and replace it by a loose nut + bolt from inside of the fender + thick rubber square ? Any suggestions are more than welcome.

Yes, sorry I couldn't make out the bracket in your picture before, but that does look like it. If you can just unscrew and remove the stud then it should work fine to use the correct bolt, washers and rubber insulator.

Worth a try. Thanks for your help Mike B.
