Here is a pic of the bump stop removed.
Its not too bad (I drove around with it
like this for 2 seasons). The caps used
were not readily available in Canada but
I was able to find some.....
If you want to make your car look as clean as possible one of the things to do is to remove the large rubber bump stops from the bumpers. The obvious problem in doing this with the 74-77 bumpers is the large hole that is left exposing the nut that is used to mount the bumper to the mount. Here is the fix:
The caps come out of the bag with a blue plastic coating to protect the polished stainless. To install, you have to very slightly bend in the metal tabs as they fit a little large. Don't bend them in too much or they fit too loose. Then just lightly tap in with a rubber mallet and they pop right in.
The caps I found are from Rona (here in Canada) They are polished stainless steel "Master plumber" caps used for blocking holes in sinks when doing plumbing work. The skew number is 452 and they are 1-1/2" size caps. I was never able to find them at Home Depot.
Done. It takes all of minutes and they fit perfectly. The bonus is they are stainless so like everything else with these cars they will never rust. If you need some contact me as I have asked that they order in more sets.
