    I am unable to find stamp dates on my fenders and hood. Found them on trunk and quarters but not the upfront parts.
    Car does have some bodywork and painted non original color.
    At some point I will start removing paint looking for original color but until then, any tell-tale signs of repop vs factory?
    On a side note, I've owned the car since 81 so if they arent original, they may be OEM as well.

    Thanks.

    Original equipment fenders will have these 3 crinkle impact areas like my fenders do in this pic.

    GM fenders have rectangular mounting nuts for the inner fender. Aftermarket will have either square or hex shaped.

    Factory fenders have an indentation just forward of the hood mount point in the shape of a T. Unmistakable tell.

    Hmm, mine are original but don’t see the T you describe. Hood mounts to hinges so that's the Area I’m looking. Any more specifics.

The crinkles are the best way to tell. OEM, they look kind of sloppy whereas AMD are intentional if that makes sense. An OEM hood has a date code on the driver side towards the rear of the hood

    My hood is original, but my fenders must be reproduction because of lack of wrinkles. How come no member is not posting picture of the "T" for badazz81z28. we need to help each other as much as possible.

    Fenders on my 71Z28 are original but not sure where the T is. Here are a couple pictures that comes closest to a T. IMG_20201016_140043470.jpg
