Most situations, you can tell by the nuts. A OE fender will have rectangular nuts for the inner fenders. Repop has what looks like normal nuts. The OE fenders also have the crash crinkles where the hood rest when it’s lowered

ok, now i know what to look for. I looked at every interior plastic part for a GM stamp, some had them some did not. Arent the interior parts all identified with something that says GM?

No, but you should see the GM part number and mfg. info molded on the backs of the plastic parts

Not all GM parts have part number stamping, but a lot of them do. I don’t recall ever seeing “GM” on anything.

GM parts fit OEM not. OEM plastic is most of the time lower grad Plastic

There should be some type of molded in numbers or GM on the interior parts. Most numbers are 1 off of the part number. Dont ask why,nobody knows. I am a GM retired Parts Manager for many years and could never understand why if you put a number on it , why its not the part number but its not. There is a chart in the parts books to convert the casting number to parts number.

I found your signature under your quote ironic.....but i knew what he was getting at.....thats funny
In other words, non OEM or aftermarket is Chinese made garbage that doesn’t fit. BTW OEM means original GM part.
