These are the RPO (Regular Production Options) codes for my 1994 Chevrolet Caprice Classic Station Wagon.  These codes are found in the trunk area of most GM cars.  This one was located on the right side of the tailgate area.  The Turbo Regal Web Page and various RPO documents were used to create the definitions for this list.
