I recently took the legbreakers off of my 73. The front looks good. I just polished up the abrasions where they were and plugged the holes with new identical chrome bumper bolts.
The rear is still frustrating me. Apparently the bumper on the 73-74 is different than 70-72. I bought some nice small chrome bumperettes and they do not swap out. The mounting holes are not even close. Shoulda checked before I bought them, but it really didnt occur to me that they would be different. So now I have to either replace the whole rear bumper - which is a shame, bc mine is in excellent shape - or put the legbreakers back on the rear. If I leave them off, the rear valance panel looks goofy due to the large empty holes for the bottom of the bumper extensions.
I am thinking I am gonna just take off the rubber pads and fabricate something nice to mount on the original chrome mounts. And I could not care less about the "purists". Sorry. Its my car.
