Re: Differnt RPO Codes
There is a SPID sticker, usually located in the console, or maybe on your year, in the cubby hole on the driver's side rear hatch area. That will tell you everything your car came with.

Re: Differnt RPO Codes
If you like you can go to www.compnine.com and they should have your RPO's for your VIN. It is a 1991, and everything I have looked up from 1990-1992 has been there.. . Unfortunately 82-89 cars are not listed... crossing fingers that some day they will be, but my hope is fading.
