I have a 1969 Camaro Vin# 124379N675991 with an engine casting # 3932388, the cowl tag says x-11. Now I am not sure if it is a true original SS or not, since there are so many little things that differ between a true ss and non ss. I have had a hell of a time finding the patrial vin, Ive looked in the two obvious spots (by the cylinder head and the oil filter and all the markings i have seen is n17 by the oil filter) on the casting date it has L17 o8. Does anyone have any information to help me. Originaly i thought i had a regular rs/ss 69, but when I began ready to sell it, I'm finding out there are many clones and fakes so to speak. I want to sell it for a fair price and know exactly what i have. It is listed on ebay area code 87031. Any information or help would be greatly appreciated.
