Chrysler "Build Sheets"
some cars had more than one ....I just found another one in my car that I didn't notice before because it was in the seat back and the back is covered by a metal cover because its a fold down rear seat in a coronet wagon.
this makes three mostly complete sheets to the same car and a fourth one was under the carpet and only a fragment so who knows if it was to this car or not but three completes with the same vin number is more than I have ever seen before. Especially for a bare bones wagon.
