Not Chevelle related, but the May 2005 issue of Super Chevy has listed the VIN numbers of the 50 cars ordered in '68 by Gibb Chevrolet. According to the article these numbers are directly from the dealerships personal records.

Thought I'd pass it along...

John:

The sYc just updated the '68 Gibb COPO (http://www.yenko.net/ubbthreads/showflat.php?Cat=&Number=102522&page=0&vc=1#Post102522) list over at the Supercar Registry, which now reflects ALL 50 numbers (with Helen Gibb's permission!), as well as sequence number and color.
