PHS doesn't have buildsheets, they do have the original invoices.

You may find the broadcast under the rear seats (most common) or above the gas tank. They are rather rare in these cars. After 1972 only the Norwood Ohio plant was building the second gen F-bodies and they tended to not place broadcasts in the car. My 73 survivor SD455 did not have one, but my Gramma's 1975 Esprit did have one under the rear seat. Go figure!
