New Car: My 1964 Plymouth Valiant

Can anyone help with the top portion of the fender tag? I have the bottom portion but can't find any consensus on the top string of numbers (1-0) or the second string of Alphabet.

Last portion reads:
SO-Shipping Order (Delivery Date) - 1112 (11/12/1964)
Number-Production Sequence - 5135
BDY-Body Style - 142
TRM-Trim Color - Tan
PMT-Body Color - XX1 (Beige)
