Does anyone know if by chance the build sheet was left in a Norwood car, where would it most likely be?

I have checked under the seats both front and rear so far.

Norwood cars are less likley to have one, but aside from under the seats. ON top of the gas tank, tucked under the dash, under the carpet, and I've heard of one inside a door panel. I found mine for my 71 ss350 on top of the gas tank and under the carpet on the drivers side. The one on the gas tank I could read the VIN and part of the first line, the rest of it had turned to dust. The one under the carpet was fadded and water stained so bad you could not begin to read it. good luck and hope you find it :)

Went yesterday to look at immaculate 80 Firebird Espirit here in London that is jaw dropping show room condition. He is selling it for 8900 Can and my buddy is serious about buying this maybe. The owner found his Norwood build sheet behind back seat just tucked behind spring of rear passenger seat. Ironically this is same spot my build sheet was found by the owner of my Z28 in 99 when he took seats out to clean. They both were in same spot from two different plants in Noorwood, Van Nuys.
