Need help deciphering this SPID

Thanks guys, yea 68bowtie that's the only truck I've seen with the same paint scheme that is a 68 swb fleet truck. I guess most people make them anniversary truck clones so there aren't many still sporting the factory scheme. Either way, that's a cool truck. I wish I had an original looking picture of that truck. This was the closest thing I could find in the thread
