X66 COPO's

[camarojoe]

A very good question that I agree I do not recall ever discussing here. I personally do not know of any non-Yenko COPO X66 cars, and highly doubt that any other dealers were aware of the availability of the 9561 package while the cars were still being built as X66's. As stated, the X66 Yenkos were only produced with the very first batch of 50 cars ordered directly by Don Yenko. By the time anyone else figured out the 427 COPO ordering process, the cars would likely have all been built as X44s or X11s. I think this is one of those "anything is possible" scenarios, but very unlikley any X66 COPO cars were built outside of Yenko's own 50 car order.
