C4 Regular Production Options
The C4 Corvette Regular Production Options (RPO) list is lengthy and each model year brought changes, additions and deletions. (The RPO list for a specific vehicle can be found on the inside of the console storage compartment lid in the form of a sticker, can often be found on a stick attached to the gas tank or a "build sheet" can be purchased from the National Corvette Museum - 800 -53-vette).
