....plus the 2 shocks, misc mounting bolts/nuts/hdwre & ribber cover & ditto at back!
IIRC it was in the neighborhood of 75-ish lbs added for F & R (IMG:style_emoticons/default/beerchug.gif) Tom /////// |

My perspective on 15 reasons why NOT to backdate the late-style bumpers, in no particular order, anyone is free to disagree. Assuming your car is not a race car or customized hot rod:
1. Loss of the cars originality - impossible to get originality back once its lost 2. Loss of the cars front/rear safety bumper equipment 3. Loss of the cars value – both resale and long term 4. Loss of the cars integrity – attempting to make a late-model 914 something it is not 5. Loss of time spent to perform the backdating 6. Loss of money spent to perform the backdating 7. Loss of early bumper parts that are only correct on early 914s 8. Loss of better aerodynamics of the late front bumper 9. Requires at least selective painting where bumper side brackets are removed 10. Requires mods to chassis for early front/rear bumper mounting hardware 11. Requires mods to chassis for early foglights mounting hardware 12. Requires mods to chassis for early horn(s) mounting hardware 13. Requires custom wiring harness to adapt early foglights to 75-76 chassis harness 14. Requires custom wiring harness to adapt early license plate lights to 75-76 chassis harness 15. Creates remnant holes through chassis from removed bumper shocks |

If you want backdated bumpers, by a backdated 914. Haha!!
However, if you do own a 914 with tits, I suggest a mastectomy. |

Wow, excellent rebuttal, Jeff! Some very good points you raise.
Since I don't want to back-date, for many of the reasons you list, I will never buy a '75 or '76. (Well, I might, if the price were right). |

For a good condition teener, the temptation is always there if the price is right.
I only brought it up because I can't believe the weight/steel they put into the bumpers. On a plus side the 76 I got that bumper off of, everything was rusted out except the bumper. IMHO I think the earlier bumpers look a lottttttttt better, but to each his own. I can see the value in either way. If we can keep these cars on the road were all doing our part. Dave |

Anyone tried to lighten the bumper by removing some of that metal? Of making a light weight replacement for the metal core? Seems like if someone want to do the trade of somewhat less strength a lot of the extra weight could be cut out. I have a '76 and was thinking about making it lighter with my cutting torch.

IMHO I think the earlier bumpers look a lottttttttt better (IMG:style_emoticons/default/agree.gif) PO backdated my 75 to body color 916 style with early style fog lights. As soon as I have the time, I'm backdating to metal bumpers and stock valances. No regrets. But then my car is a 2270 with naca ducts in the rockers to the external oil cooler, 911 suspension, tangerine headers and exhaust, etc etc etc. Going back to stock bumpers isn't really an option, and would probably degrade the car's value anyway. The 914 didn't get it as bad as the MGB, but IMO the metal bumpers are preferable in either case. |

I got 99 problems, but backdated bumpers ain’t one. Parallel parking places are a fact of life if you ever drive your 914, so if I had a 914 with late bumpers I would not be in a hurry to backdate. But then again they only help if you don’t lower the car…

I took the front bumper off my 72 and it is surprisingly light. I guess I was thinking of the old heavy GM bumpers but it almost feels plastic.. My ex gf loved the 75 bumpers so I will just go throw them in her yard....

Really the reason they get back dated is obvious to so many people wanting less weight, cleaner lines ,not sure about the safety issue ,as they did with the 911 it was only to get around the 5mph crash laws (1974 ?),BMW managed to ugly up there cars so bad with this. Car makers of the time that imported to the US had all sorts of not so nice solutions,same with smog control, however that's another topic. All these so called safety bumpers did @ the time was to cost the owner/insurers more in repairs. I can't see Mark @ 914rubber replicating them in a big hurry but I might be wrong. |

There is a thread about how to make light late bumpers
http://www.914world.com/bbs2/index.php?showtopic=89595 I shaved about half of the weight on my front bumper (about 7 kgs) ... Rear one still to do. (IMG:http://www.914world.com/bbs2/uploads/post-5409-1337535838.jpg) (IMG:http://www.914world.com/bbs2/uploads/post-5409-1337535850.jpg) |

I would buy a '75 but I would have to backdate the bumpers. I could not buy a '76 due to CA smog laws still requiring that car to go through smog checks for licensing.

The Haynes 914 manual shows some of the differences. |

I used to hate the 75-76 bumpers and blamed them for the ultimate demise in production of a great car.
Now days, I actually am fine with them. I still hate the 75-76 turn from basket weave interior though. |
