This is a UOIT by Fisher. I found one of those in my 67 LOS coupe and from what I was told, it is rare to find these.
IMO, this is just as valuable as a broadcast sheet found on top of a tank, though not as detailed. But it does verify the trim tag codes.
One thing I want to point out is the VIN is a month past mine and the top rivet on the door tag shown looks almost round, which one on my coupe is like. I have had the usual 'doubting Thomas' experts say it was changed because it didn't have a well defined star pattern to it. My reply is I tell them they should be embarrassed to make such a bold statement like that. Then again, these were some of the same 'experts' that told me "strange....I have never seen an SS 396 without factory gauges before".

I would suggest just saving pictures and information on cars similar to yours. The "doubting Thomas" type of guys usually are know it alls, and have little to no clue about discrepancies (variance) . I have had the same experience but with my rear end stamp, even to the point where a moderator questioned my original paperwork, and authenticity of my car. I have since located some examples similar to mine in the same time frame, or in one example the same shift, that my rear end was stamped. So no worries on my end, I know what I have, and that guy will stay clueless, like the guy you ran into.
I like the 67, but he doesn't provide much detail if the car runs or not. I a guessing it was a saginaw trans, that someone has upgraded to a hurst linkage. What is the large box on the drivers side fender well? (something RS headlight related?)
