I've been looking for an OEM front fender and a source I found has one that's marked GM DOT on the inside. Never heard of this until I saw the pic he sent me. The owner claimed it to be an authentic GM part. I thought all GM body sheet metal were labeled beginning with an alpha p/n. I googled it and there is a company out there called GM Parts, but disclosure states it's not affiliated with General Motors. If anyone can shed some light on this, it will be truly appreciated.

Thanks

 

 

It's definitely a GM replacement... My 87 had one on the driver's side (I still have it but it's in the garage). There are 2 stickers, one is the GM DOT sticker and the other is a part number, which may have come off by now. I know mine has.
