    A couple of other Fchatters contacted me about making a set of front bumper mounts for their US to Euro conversion projects. It's not something I have the time to do, so I contacted a prototype shop that does a ton of work for us at GM. These are great guys, and they do fabulous work. This is a small job for them, but would keep somebody busy for a day or so. With times as slow in Detroit as they are, -and as a favor- they'll make these things for me at their cost. That amounts to roughly five hundred dollars per set if they make two sets. Should they machine five sets, however, the price would drop into the three hundred range. The Euro bumper conversion seems to be a fairly popular modification, so I thought I'd see if a few others would be interested in saving themselves the aggravation of having to make their own.

    As I mentioned, Cobra does really fabulous work. These would be CNC'd fom billet, and then anodized black. The ones shown I made. They're not flawless in appearance, but they work perfectly - allowing bumper adjustability in all three planes.

    So... IS anyone else be interested?...

    If the price is right I'd want a set as I'm planning on picking up Euro bumpers from rennspeed on Ebay ($385 per bumper is too good to pass up)

    Regards,

    As listed in the original post $500 a set if two sets are produced...drops to $300 a set if 5 sets in total are made. I'm interested, however likely at $300, if infact they will work with Rennspeed bumper which is moulded from a true Euro bumper. I guess this means that 4 more people ar needed.

    I'm sorry for the delayed replay, but this is the first chance I've had to respond.

    The cost of making them is going to be dependent upon the number made. Much like a party, the more the merrier.
    The bumpers I used were reproduction jobbies sold by Jim Carpenter. I think these are from the same source as those peddled by Nick of Nick's Forza, but don't quote me. Jim claimed the the mounting holes were in the same location as the factory Euro bumpers. There's not a lot of room on the back side of the these, so I imagine mounting points for all the repros are going to be within the adjustment capability of my mounting brackets. Should enough people show interest, however, I'd like to get some measurements from everyone just to make sure. And modify the design if required...

    The prototype shop will make any number of these things that I want. If you're the only guy buying them though, you'll have to eat all the set-up time.

    DenisB, I cannot answer your question about the Mondial 8. Perhaps somebody else out there can?...

    First, I have been seeing a bumper reducer on ebay for about $135. Why reinvent the wheel? Second, I looked under my front bumper and it appears that you could take the existing mount and cut it down a few inches then reinstall the same one for free. Am I wrong ...what am I missing????

    the true euro bumper has an offset on the mounting points, the holes dont line up!! so, it is not just a matter of shortening the tubes, or you cannot use those shorter tubes found on ebay with the euro bumper. those ebay bumper tubes are made solely for the US bumper and will not fit the euro fiberglass bumper because of the mounting holes being offset - that is why the need for conversion brackets to bring the holes into allignment.

    Is it fair to say that if you want to move your US bumper back, (to the same position as the Euro Bumper) all you have to do is shorten the existing bumper mounting tubes?

    Or, just drill a little hole in the bumper shocks and push the bumper inwards. Takes just a few minutes, and this is what you get (and though of course you don't save any weight this way, you do retain a true protective bumper):

    I appologize in advance because I really should take the bumper off and look at everything before I ask this question. When I look under there I see the tube with the bracket on the end going to the bumper. What is the shock? and where do you drill? Is the shock behind the tube and I have not seen this yet? Thanks for all the info I really appreciate this.

    I bought a set of the modified mounts last year and slid my US bumper back. I have the factory stock mounts I removed if someone wants them to modify PM me. Joe

    Ok, drill a hole in the shock and push the (front) bumper back,is that all there is to it? If so, and you can't do that in the rear,whats the poor man's way of ''euroizing'' the rear? Remove the bumber,remove the shock and replace it with a shorter tube with plates welded to the ends and of course drilled to match the bumper mounting holes?
    Thanks in advance.

    detroit; Your car looks great with the copper colored wheels~

    Mike C; Like a sexy chick.. your car always looks hot! I think it must be the stance combined with the euro spoiler and bumper.

    I'm trying to manage my projectitus and get a couple of Porsches finished prior to tampering with the F-car. With threads like this, you guys make this hard to do!

    Anyway, my assumption is that if you drill the bumper shocks you ar doing so to releas the pressure/oil thus allowing them to be pushed back. Do they need to be welded, ot have another hole drille once compressed and maybe a set-screw installed to hold them in place? Just a thought.

    I'm also curious about the fix for the rear look.

    Thx,

    Paul

    I have not done my rear bumper yet because I just bought a tubi last month and was going to do it all at the same time. But from what I can gather from Fchat and looking at mine, the rear is fairly simple. Unbolt the bumper, remove the large spacer blocks, trim the bolts down and re-mount. Unless I am missing something the rear is very easy to do and an hour at the most. And oh yes, you guys have an extra set of hands when you start removing these US spec bumpers. They are heavy!

    I just took apart my front end and I now realize there are shocks on the tube. I thought it was just a tube. I have the same question and concern, will I blow myself up if I drill a hole into the shock? Also even if I drill the hole, I would still need to compress the shock because on my 84 QV there is a metal plate the shock is pushed up against that won't let me go back any further. My bigest concern however, is obviously getting blown up!!! Also I did my rear bumper a few days ago. I took out the metal (heavy) spacer and you are right ther bolts are too long. I went to Tractor Supply Store and bought polyurthane bushings 1/2 inch, put 4 on each bolt and tightened it down it came out perferct. However, I am asking for those tilting metric rachet wrenches at Sears for fathers day. You will soon discover what I mean. Good luck, and someone get back to me about the shocks, I am gaing to wait until I get some reassurance or better life insurance.

    I saw another article on FChat about drilling a bumper shock and it appeared safe top proceed so I did it. I used my drill press and when it went through a spray/mist shot up for a brief second. I then used a screw clamp to compress the shock which had the dual effect of draining the oil out of the shock tube. I then reinstalled it using the same holes. At this point my bumper can still be moved in and out. When I reinstalled it it was very helpful, because the nuts on the back are difficult to get on when it is pushed way back. I also figued out that if you tighten down the metal clamp with the rubber bushing too much it throws off the holes on the bumper...so wait to tighten that down. My plan is to eventially put a self tapping screw into the shock to prevent it from moving at all. However, it is actually pretty darn good just the way it is and it could be left alone. Finally, one last helpful hint put the lights up when working on the bumper shocks, it opens up all the room to get wrenches in there. All in all very easy project and it improved the look of the car ten fold...it is now closer to the way the designers intended.

    I didn't take pictures. However, I have pictures of the car before, but you have your car so I am sure you are not interested in those. I will take some pictures this weekend and post them by monday for you. I would highly recommend this it really looks great and it was easy. As some one on FCHAT said this is the poorman's euro bumper. After doing this and benchpressing both of these heavy bumpers over my head while trying to get the bolts back in the bracket, I can understand why people are interested in the real fibergalss euro bumpers. I think replacing the bumpers could shave 100 pounds off the car. For now I am really happy with my end result, especially for the price. I would be happy to give you any details you need. Last, I don't know how to post pictures, can you tell me?

    Looks like a well-designed and built product, but I'll have to pass, with very great regrets.

    My car is insured as stock American-spec; messing with the bumpers could lead potentially lead to big trouble in both the collision and liability areas.

    If there's another 308 in my future, I'll make sure it's Euro-spec before sending the $$$.

    Those ugly old US-spec bumpers are mighty reassuring in Dallas traffic.
