I have a 1975 chassis that I'm backdating the bumpers to early style. I have the new bumper holes drilled no problem. The question I have is regarding the front bumper " lip " that I guess I have to remove ? This " lip " is where the ugly rubber cover slid over. So first question is I do have to remove this lip correct ? Assuming I do I believe I need to use a spot weld bit to drill out the spot welds ? I've never used one of these can someone give me a quick walk thru on these ? Is it as simple as drilling them out ? I know I should " search " but I'm at work most of today and they frown on too much 914 content (IMG:style_emoticons/default/biggrin.gif) .

I bought a spotweld removal tool, about $15.00. You center punch the spotweld so the pilot on the tool doesn't walk, then just drill through the attached piece you want to remove. Only drill to the point of breaking out the piece from the weld, you will be left with a spotweld slug you grind off. Simple as pie. (IMG:style_emoticons/default/beerchug.gif) |

I went to Harbor Freight and bought a spot welder cutter/bit for $4.99. Worked great but I got a little aggressive on some of them (IMG:style_emoticons/default/dry.gif) . Anyway I got the lip off and I'm moving forward with the bumper install. Thanks guys (IMG:style_emoticons/default/beer.gif)

The rear bumper also has a suport that welds onto the body for the center above the licence plate. I can produce mine with out the mount if you don't want it.

That is good to know! When I order my rear pad from you I will be sure to specify. I am currently running mine without a support. |

The suport still runds across the other two corneres, it just dosen't have a mounting stud, but I think you got the idea.
