Hey all Doing a rebuild of the front suspension on 72 LeSabre. There are a couple of rubber bumpers on the under side of the UPPER control arms. The service manual just refers to them as "bumper". What is unique about them is that to insert them, you push a section of rubber about 1 inch long thru a slot in the control arm. Rock Auto doesn't seem to have them and I am not sure where else to look. Any suggestions where I can find this bumper or even what it is called? I foolishly shredded the thing getting it out before I had a new one in hand. In the picture, I am holding the push thru part next to the slot it goes thru, but the rest of the bumper is not in picture. Appreciate the help!
