Is my truck rare?

[67chevy_hotrod]

So I have a '67 C-10 original V-8(which unfortunately is long gone) big back window, factory air conditioning, and a tilt column. I ran the VIN cause i figured the cab was probably newer due to the big back window buts its a 67. I checked the partial on the frame to see if the truck was maybe just a mod-podge of parts, but it matched. The VIN says its a 1967 with a V8 that was built in St. Louis. I have no reason to believe that someone went to all the trouble to put a big back window, tilt column or A/C due to the dire condition of the truck. If someone had done all this work you would think that the floor pans would have been in better shape because they are gone. Rocker panels are swiss cheese and the truck had crappy primer over all of it when i bought it. It has had several resprays but the paint under the VIN tag is like a maroon. All the re-sprays appear to be a crappy Maaco type deal.(Overspray in the vents, jams weren't painted and there was no prep under the layers of paint.. it went crappy primer, then terrible metallic blue still shiny, then a hugger orange like color still shiny then primer and metal. WHAT IS GOING ON i was thinking peeling off layers of paint lol. Please lend any info you guys have! Thanks!!
