    I am thinking of upgrading my steering box in my 80' to an 87' z28 unit.
    Couple of questions:
    Anybody deal with American Camaro and Firebird in OKC?
    Seem pretty straight up.

    Also, it seems this is fairly straightforward. Any tips, tricks, things to look out for when doing this?
    All my other components are being replaced with ProForged products.

    Thanks.

    I put one in my 81, and it couldn't be simpler. Your '80 probably has metric pressure and return line fittings, so the new box shouldn't require any adapters for your lines. Complete bolt-on.

    About 2 years ago I bought the 3rd gen IROC box directly from GM to install in a customer's 81 Z28.

    Also....speaking of lines....I have some gnarly Frankenstein ones on there now.
    Would like some part # for some the stock power steering hoses. Ones that hug the gearbox pretty tight.

    If I remember correctly it was under $200.

    They are a junk yard, they sell used parts.

    The GM one I bought was brand new, not a remanufactured box.

    Do you have the gm part # or where you got it from handy? I have a manual s10 box in my 81 now. Quite frankly it sucks compared to a de-powered rack and pinion in my daily. Having a few shop cars with rack setups, I looked into that. Seems that's a hard no. I hate clutter but I can make a power box look nice.
