Found in a 71 Monte SS that was next in line. I'd be happy to reunite it with the owner.

Nicely Equiped; wish it was mine and the build sheet is in great condition!!

That isn't my build sheet.
But I did find (in my 1972 SS-454 El Camino) a build sheet for the Monte Carlo that was following my car down the assembly line.
