When I bought my car a couple of years back I found these in it . one was in the glove box and the other one under the seats. I see codes on them that seem to be items on my car . are they of any signifigance , what are they called. thanks Al
Fisher Body used these codes to know what options to assemble into the bodies. We found (2) also in my car, one behind the drivers seat back and another under the passenger seat.
