For 69 it should be 124379N509224. That is the VIN so not much can be told from that except that it is a coupe and not a convertible, however, the 509224 could indicate if it fits into a certain month for the build date stamped on the trim tag if you have that info as well. Additionally there is a decent website, Camaro Research Group that can help with anything you need to know.
