fender tag Decoding Values

Wow! Such quick and helpful replies! Thanks Much to Dana67Dart for decoding and providing references. I'm thinking of restoring the car sans the drive train. I was curious to see if it was factory air. When I got the car 20 years ago it had an old and very tired 50's Hemi with AC. Since I've updated the drive train now 440, 4spd with 8 3/4 rear end with the MOPAR stock AC unit. I was thinking of deleting AC but since the tag calls for it may not. Thanks much to all who responded - very helpful!
