This has probably been asked many times before but since I'm new on here, can someone tell me how to decode the last six numbers on my serial number plate reading 051990? These should show the production number of my truck but how do I read/interpret it? I understand the first four letters & numbers but am not certain about the last six numbers. Also, anyone know approximately how many '54 Chevy 3100s were manufactured in 1954?
Thanks for your help.
