Fender tags were made for two reasons in my opinion. It was the only way to have build information during Body-In-White welding as a paper broadcast sheet would either be peppered with welding spark burn holes or actually catch on fire LOL. The second reason was for the corrosion dip tank and paint department and obvious why a paper broadcast sheet might not be legible after running through those operations. That's also why the metal fender tags have raised characters and not just a metal tag with non-raised information on it so even if painted you can still read the tag/info. BTW on a 1969 Lynch Road fender tag there is little or no information other than what's needed in Body-In-White and the paint departments. I will wait for the flame to arrive on this shortly but if you dig deep you'll find as I said "little or no information" other than what's needed in Body-In-White and paint.
