    Does any body know the weight of the front bumper on a '79 with the aluminum inner and also the steel core support, trying to decide if a custom core support and glass bumper is in the near future. There's not alot of lightweight parts for this car that I've found so far and I already have a fiberglass hood. I really dont want to put a factory aluminum support in if Im tearing it apart anyways to get the steel one out, I would probably just build a custom one. Thanks

    if ya wanna lighten the bumpers..........easiest way is simply chop it up. if ya look at the bumper and core support ya really only need a small part of the core to bolt the bumper on. pretty sure you could chop away at least 60 to 70 % off it and still look stock. as for strength well its probably pretty weak that way. but super light


    peace

    I know you have a '79, but this may help anyways...

    81-88 Cutlass Factory Component Weights:

    --------------------------Aluminum-----Steel
    Hood----------------------22.5 lbs-----53 lbs
    Rad. Core Support------12 lbs--------24 lbs
    Intake Manifold----------17 lbs--------58 lbs
    Brake Drums-------------9.5 lbs------12 lbs
    Front Bumper Core------8 lbs---------25 lbs
    Rear Bumper Core------11 lbs--------35 lbs

    You'll probably be better off buying a pre-fabbed lightweight radiator support or making one yourself...
    Finding a factory piece is a pain, unless you're Lue. And they're expensive, because the people that do find them know what they're worth.

    Don't have any numbers to help but I did the following to my Cutlass.

    Fiberglass bumpers (front& rear), custom aluminum bumper brackets, Aluminum core support, Aluminum radiator,fiberglass cowl hood.

    Some weight was added Pontiac 440, th400, 12 bolt and rollbar.

    The car ended up 3250# race weight, 225# of that is me.

    I also used an Iceman trans crossmember 8#, awesome piece.

    He also sell a core/radiator support. In the future I might swap the aluminum one onto my wagon and add his.

    Forgot, I saw an ad for a aluminum hood also. They are supposed to be lighter then fiberglass. It is pricey also.

    I would not use the aluminum one if you plan on a scoop of any kind, why ruin a neat factory part?

    shotgun ,
    have you verified the weight difference between your fab hood and the original steel one ?

    Thanks for the replies. Does anyone know if the iceman core support fit cutlass also. He has them listed for a malibu and also wondering about price? To my knowledge any two headlight core for g-bodies are all pretty much the same.

    Bigdan, No. I never weighed the stocker or glass. I could unbolt the glass one if you really need to know. It's kinda beat up and in black primer so I don't have to worry about scratches.


    gbodyaddict, THAT"S MY SPREADSHEET. :lol: Good to see it is being put to good use. I do need to update it abit.


    oldsrcr, my understaning it will bolt in. With any install, things like headlight buckets etc may need you to do some minor fab.

    Send me one of his, $150 bucks and a return shipping label and you can have my aluminum one. :wink:
