First, my truck is a 53 Chev 5100S COE. I have two small flat plaques, top of the dash between the radio and windshield that I am trying to identify and refill with the original message. I read somewhere that they originally contained directions for the use of the 2 speed rearend, PTO or maybe even both. Does anyone know, and if so, how about a snapshot so I can duplicate. Thanks, in advance.
