I have a '69 SS L48 (350/300) with VIN ending in 690228 and an X11 code on the trim tag.
Trying to figure out how many were built. I know that total Camaro production for that year was 243,085. I followed some of CRG's deciphering and figured out that 187,185 out of that total were non-SS cars. From there, CRG walks you through what percent of the remaining 55,910 were Super Sports with X11 code.
Well, I managed to get myself totally confused with 9% of this and 5% of that and couldn't quite come up with a number! If there any scientists out there that can help interpret this stuff (someone from CRG, perhaps?), I'd appreciate it!
Here's what I found in CRG literature:
So, how many cars were coded X11?
Some quick math yields that 77% of 1969 Camaros were non-SS and non-Z28. After Dec 68, these cars would be coded X11 and X44. Multiplying the that percentage with the percentage of cars that had style trim or RS (58%) yields a little more than 44% of X-coded 69's were non-SS X11's. A similar calculation on the SS350 (9% of 69's) production quantity yield that less than half would be X55, the balance would be X11, about 5%. Adding these totals together shows the total of X11-coded cars to be approximately 50% of all 1969 X-codes. The corollary is that only about one in ten of X11-coded cars are actually SS350's.
