How To Identify 1st Gen L-78 ...........

[CamarosRus]

While at The Charlotte Autofair I saw several 69 SS Camaros for sale, one with a L-89 no less and another L-78 as claimed by the seller. Neither car had any documentation what so ever. I have the old Camaro Enthusiast magazine from 1994 that explains some of the X-codes........but would this boards members please tell me some facts about L-78 and 1969 L-89 trim tags and other tell tail signs.......thanks, chuck
