Regular Production Order. These are the codes that GM uses to identify options.
For example, LT1 is the RPO for the engine used from 1992-1996.
The RPO codes are printed on a sticker, depending on year, the sticker is either under the center arm rest, or under the rear storage bin lids. Take your pick. Use this sticker to determine the original options and to see if the stickers VIN matches the car. The National Corvette Museum can provide you with a copy of the build sheet and window sticker for a nominal fee.
