    Sport bumper holes, plug or not ?

    Bumper experts,

    I'm getting this sport bumper painted to match the car. I've seen repros and most are clean and completely free of holes. This one is the real deal - metal, and as you can see (and probably know) it's got holes (blue) which I assumed were for the overriders but I really don't know. I want to go bumperette-free for looks - I've seen some original cars with a plug in there so I thought this was a stock hole... My questions are 1) is that plug findable / is that hole legit ? 2) what's the small hole below (green, one on each side) ? not stock? Should I get that filled ? 3) if I start filling, I might get the center holes plugged too (I assume for license plate) and pay the fix-it ticket, so in for a penny, would you fill everything ( blue + green + center) or is it bad form to plug a real sports bumper's overrider holes (if that is what they are, the blue ones) ? I like to keep things stock, it's not much more $ to fill it all but I'd rather keep it as it should be...

    While we're at it, I've never transplanted a bumper before, is there stuff I should be buying to swap ? I have a new rubber trim and I plan on reusing the metal base from this one (I'd like to reuse the rubber trim but I imagine it's dented by the bumperettes). Thanks !!

    If that is a steel sport bumper, either use it with the holes and bumperettes as-is, or get a CF or Fiberglass one. Can't imagine why you would want the extra weight if originality was not a concern.

    One persons opinion: I would fill (with Steel) any holes in the bumper that were NOT drilled at the factory. I would buy body plugs to fill the holes from the bumperettes.

    That's exactly my question: which ones are factory, which ones aren't ? I'm pretty sure the license plate holes are not factory, but the bleu and green arrow ones ? No clue.... I've never had a real sports bumper before..

    To answer the previous post: It's not much heavier than the non sports bumper I have now, and weight up front doesn't bother me too much. I had a replica on another early 911 before and I remember it did not bolt on as well... Thanks guy, keep'em coming, I'm not sure about those holes !

    To answer your question , I've seen numerous cars with factory delete front bumper guards listed on the COA . The bumpers had holes with opaque plastic plugs , like the hole at the blue arrow in your picture . I think the hole at the green arrow should be patched along with the license plate mounting holes .

    Weld all the holes and grind smooth. IMO looks good for a hotrod

    I had 2 '73s with the steel "S" bumper, one had over-riders and the other just had the rubber plugs. Replaced the rubber plugs on the one, and removed the over-riders and installed new rubber plugs on the other, also neede a new rubber strip once the over-riders were removed.

    I have this listed as the part number for the plugs, 311-611-849. It was no longer available from VW or Porsche a few years ago, however VW has a newer replacement part (8A0-831-449) that fit perfectly .

    Thank you very much. Looks like what I'll do... It's really cleaner without overriders...

    It's happening... Match was done on my hood... Always scary but it washes off....

    Bumper is now off - Looks like I might need a new seal from behind the aluminum trim, the rest looks reusable !

    Done...some comments and tips below...

    Reaching some of those bumper bolts isn't fun, nor as I found out is threading the new rubber trim on the base, or attaching that deco to the bumper without scratching the hell out of it.. Lots of blue tape was used and some swearing when tearing/peeling it off ;-)

    I have plugs painted to fill the overrider holes - wanted the bumper stock... (not yet shown here)

    The 2 tiny holes at the bottom are for a plate but they were serious metal inserts so I did not get them filled only to have to redrill them later when I got my first "fix it" ticket - it's a clean insert... Will take beauty pics later...

    Thanks for the tip on the 1 piece rubber trim. That is also a trip, because it ends up 2" too short on installation and you have to convince it to slide a bit and make length which is not fun at all unmounted (I'd do it when mounted on the bumper at one end and 90% installed, for better application of force next time). In some ways the 3 piece option, cut to fit, is much easier and I found out that "shoe goo" in black matches the gap really well, but the 3 piece set"ends" are wider than the center part, which is lame, so prferably buy the $$$ 1 piece rubber.. I did both sequentially but ended up using the one piece because I'd bought it anyway and it looks much better..

    Another surprise was how dented my original bumper was from the overriders despite the trim piece on those - big grooves there from overtightening or no seal at soem point the life of the car ? I cannot even resell it without reworking the stock bumper unless someone wants bumperettes with.. meh. You can see even the rubber trim base has 2 grooves from that on the left side of the pic from the overriders, but replacing the base trim I understand makes for terrible fit so I reused my stock one and the hell with the little groove.

    Love the Sports bumper minus overriders look - need to re-tilt my left side TTL light too, I must have bumped it...
