['ol Pinion head]

the only broadcast sheets I've ever ran across between the carpet or vinyl flooring & floor insulation were in Pontiac plant A-body's, & they were stuck on pass side of front floor tunnel & heavily soaked up a coationg from the black tar paper covered type underlayment. Pontiac plant broadcast sheets are the small style like the last one posted by BVZ.

Arlington plant, have discovered quite a few, the last one was only a partial & was above the glove box area taped to the inner shell of a '70 dash. Above the gas tank, under original rear package tray, if car's pkg tray was not hacked for 6x9's is another place they occasionally show up. Early '70's Lakewood plant built A's & GP's, behind the drivers side door panel, most will have one if door panel & water shield have not been disturbed.
