Entirely wrong forum and It's been answered numerous times but hey, I dislike the search function here sometimes anyways. It's short for Regular Production Option. It is the coding system GM and other auto manufacturers use to distinguish what your particular car was built with. WS6 is a performance package, LO3 is the 305 CI TBI engine, G80 is limited slip differential and etc. Your list should be in the hatch, drivers side lockable storage compartment. It should be on the plastic door with the Keyhole. Camaro's have them in the glovebox as do all verts if i'm correct.

Not that I'm aware of. The only two locations I've ever seen them are there. Inside the center console or in Firebirds and TA's inside the rear storage area that can be locked on the drivers side. Might have been replaced and the sticker wasn't saved...
