Where can I find out what option designation my 1988 C4 has? I have the build sheet from the tank and the RPO list from inside the glove box, but do not see a 1LT, 2LT, or 3LT designation. Did the C4s have any designation?
You must be thinking of "option package" codes that were/are used on the later model cars. An '88 doesn't really have anything like that other than the Z01, 35th anny option, and the BK2 Calloway Twin Turbo.
