You would be surprised how much the people on this sight know about these cars! With some detective work and their help, you can probably figure out what it probably was and wasn't. Little things like spring type, speed-o cable penetration, light placement, trim, etc. can be used to rule things out or make it possible to have certain trim groups and other packages. Though, if you have my luck, you may never know... These guys are good people and, like me, love a good puzzle to solve.
