Is there any way to figure out what the build date for your car was without a fender tag or build sheet. Fender tag isn't there and I haven't looked for the build sheet but am figuring it's probably not there. It's in winter storage right now. I have figured out almost everything without them. I bought the car from an owner that has had the car since 1984. He knew the original color, what the engine was and that it was a 4 speed from the factory. Also the interior. the order number on the radiator support and trunk gutter also match.
