Re: Got the truck moved today!

SPID
Service Parts IDentification.
GM uses them to this day, stuck somewhere on the car. But now it's all in code.
If the SPID gets full of options, then the assembly line was directed to add the remaining options on one half of the second spid, and then cut it in half.
I'm interested to see what you got there Brad.
