    Default Fiberglass bumpers

    Hi.

    Does one of you have any experience with mouting the MSA fiberglass bumpers (50-1750 & 50-1751) on a 1974 260Z?

    Thanks

    Is your 260 an early production car... prior to 8/74 ?

    The delivery date in the guarantee booklet states 12-1974. And the turn signal lights are in the grille.

    That is considered a 74.5 or late production date. The late/74.5 260Z is very similar to the 75 280Z...larger bumpers, lights in the grille,etc. . The early production date is very similar to the 73 240Z... smaller bumpers, turn lights below the bumper etc. .

    The 1750 and 1751 bumper kit you have is designed to be used with the earlier model Z's 70-(early)74.

    The catolog lists: 50-1750 Front 70 - early 74 and 50-1751 Rear 70 - early 74

    The problem you have is that the kit was designed for the early models with the smaller bumpers, turn lights in the lower valance and rear sheet metal differences.

    Bottom line... it's not impossible but you are facing quite a bit of additional work and parts for it to work.

    And what about the 240Z metal bumpers with the 240Z brackets, will that work? My car has indentations behind the safety bumpers.

    Hmm, all bets are off for cars originally delivered in Europe. I don't know for sure, but I was under the impression that Europe (along with the UK, Oz and Japan) never got the later 280Z body. They did have the signals in the grill, but other than that I think they had the earlier shell.

    On the other hand, if it was originally a US car that was imported later, the above post is correct, and the same issues apply to the 240Z bumpers as well.

    It is a US car. It was originaly deliverd in Spokane, WA. I imported it to the Netherlands a few weeks ago. So am I facing extra bodywork, or just work on the bumpers and brackets for mounting?

    Not so much bodywork, but there are no brackets that are pre-made for bumper retro-fitting. You will have to custom fabricate the brackets. It can be done, it's just more work.

    So european or 240Z bracktes will not work as a bolt on mounting.

    They could in conjunction with some additional custom fabrication. If I am not mistaken you will have to weld in threaded plates to the back of the valance and lower side fender for the rear brackets to work.

    The front is going to require the entire lower valance with turn signal lights etc. beyond that I am not that familiar with the later larger bumper versions.
    I would have to look at it closer.

    Arne... you were doing pretty good. Perhaps, you can help him further.

    Like...I said earlier... it is not impossible. It is going to require fabrication and additional parts from an earlier model for it to work.

    Post some pics of the front and rear.

    I'd love to, but at this point we have reached the limits of my knowledge on this. Anything I could offer from here would be pure speculation on my part, so I'd rather wait and hope that someone who has done this weighs in instead.

    I do think that the front can be installed without changing the valance and turn signals, however. At least, I'm certain that I have seen cars with the small bumpers on them with the later valances.

    I am with you there. Also, I believe your correct about not needing the front valance. He would just need the tun signals.

    I think when you don't use the bumper guards, just the plain bumper the turn signals can be left in place. The smaller bumper wil fit underneath the turn signals. Also it wil give a cleaner look without the guards.

    While I have no idea what it takes to do it, the attached picture proves that no light or valance changes are needed.

    And no bumper guards.
    Maybe a black mesh-grille in the valance will make it look good.

    I found that my car has two towing-hooks attached to the rear body. Is this a good mounting point for early Z or fiberglass bumpers?

    If I'm orienting the picture correctly, you should be able to fabricate some brackets that use those mounting points, yes.

    They are located on the inside of the shocks at the point where they go through the bodywork.
    For orientation you should rotate the image to the left. It is a picture of the shock/tow mount on the right side of the car (standing behind it).

    That's what I thought. In that case, the mounting holes for the tow hooks are similar to the mounts for the early bumpers. You won't be able to use the factory brackets, but it should be easy to build something similar.

    You can see the bumper mounts in the picture of my car in the link below:

    Looking at the pictures on your site I notice that the indentations on the rear sides of the car stretch more to the wheel arch than the indentations on my car.
    The rubber side pieces on my car are shorter than the metal side pieces of the earlier bumpers. Is this going to cause me problems when fitting earlier bumpers?

    I don't really know, since I only have experience with the early cars.

    I know I've seen information on a website about replacing the late 260Z/280Z bumpers with the 240Z bumpers, but I can't remember where, maybe try a google search?
