I have an LA built 70 Cuda...no build sheet, I was so bummed as I was looking in all the places, and then I read this thread and felt a little better, probably never had one. Not sure if this matters to anyone, but I thought it was cool, this mark was by the driver headlight and I saved it when I had the car painted...and because of this mark (and some thoughts from Moparts folks) I kept it this color..I think my painter thought I was nuts when I told him to mask this off and not touch it...
