I think those are factory equipment codes, usually in the glove box. If you look them up, you'll know what size engine, transmission, axle ratio, ac/non ac, etc.

I checked the codes for my '87 against the info posted on this site. A lot of the codes listed on mine didn't have any information listed. I was hoping to find an axle ratio listed before I have to pull the covers to find out.

The order number is just a random number to tell the assembly line worker what truck gets what, from what I've seen they are quite random.
YD5 - SPRING FRONT , BASE EQUIPMENT
BW3 - Advance price sheet
XYT and YYT - 235/85/R16 tires front and rear.
