Let's call them anomalies. It's original to the car. Could be a 3 or an E, and yes an M. Does anyone else have them in this location? As we now know, don't look at it in the upside down. This car was built before Stranger Things...lol. But seriously, the Norwood plant was pushing remaining Birds out the door as 1969 was closing the Fbody. If it was silver, and someone wanted white it got new paint. And...maybe....the AEE code on cowl tags represents a factory change. This i believe because only Norwood had these AEE codes and only for 69. I think mine was repainted from Palladium Silver, which was already on the tag, and the factory added AEE. In fact, my cowl tag appears to be re-riveted. I would ask, also, if any '69 Firebird cowel tags with AEE appear to be reaffixed.
