    I dont think they are part number stamped if your looking for year specific parts, the lugs were used for many cars and years. and yes reproduced.

    1970/72 Lugnuts have never been reproduced accurately.

    AMES Pontiac Performance (and others ?) sell a reproduction of the 2nd design
    lugnut..........with the shorter "crown"

    Thanks for the information. I was hoping the first gen was being reproduced.

    Hmmm never noticed this difference. learn something every day.

    I know I used to hate those stainless caps when I was a mechanic 20 years ago, they would shear off and get stuck in my impact socket.

    Looks like a "material on" condition to change the 2nd design to first design in a lathe. I've got a complete set of the second designs. Anybody have an original that I can get some dims from?

    I've read that the Pontiac guys have a source for lug nuts that are closer to the GM originals.
    Ames Performance shows one that if the picture is correct, it is close to original GM

    Search for part T118

    Somebody who wants original looking lug nuts should order a couple of these and compare to original GM 1970 Z28 ones.

    The lug nuts in your link are the standard steel nut used for cars with hub caps...
    The lug nuts pictured above are the type used on Z28 & rally wheels, which do not use hub caps.

    I agree, The lug nut from Ames looks close. Photo on their website says 'Actual' part.

    Here's a direct link to the part...
