RPO Codes 
"I want everyone to realize that many of them are NOT RPO codes. Rather they are Build/Service codes. The difference is that RPO codes are the codes with which the dealer ordered the car. RPO stands for Regular Production Options and as such are all one needs to determine what options were built into the car at the factory. The B/S codes are redundant to the model, year, and specified options and are therefore irrevelant to the owners, other than for sake of intellectual conversation. The B/S code items were NOT available separately and therefore NOT "options." These codes were put on the S.P.I.L. in order to aid the factory in building the car and for the dealer to properly service it."
