Was reading posts over on the NCRS forums and ran across this little bit of information which JohnZ stated. I knew there were issues with the new model, however I do not believe I have ever seen the specific issues stated or discussed either here, Yenko.net, or Camaros.net.
If this is posted somewhere on the CRG I do not recall seeing it.

The extended production year for the '69 Camaro (and late start for the new '70 Camaro) was a result of die tryout failures for the new Camaro quarter panel dies. The die tryout panels exhibited numerous wrinkles and splits, and it required major changes in the first-stage draw dies and draw clamping rings to work out the forming issues before the quarters could be made reliably at production rates. There are lots of "conspiracy theories" that folks like to relate, but they're hogwash. Fisher Body had to do a lot of carving on draw dies and draw rings, and that delayed the program; first time Fisher Body Die Engineering was ever responsible for a delayed launch. Involved a lot of wild last-minute scrambling by both Chevrolet and Fisher Body Purchasing to get both inside and outside suppliers to keep making 1969 parts on lines that were supposed to be in the process of being changed over to the new 1970 parts.
