Kevin,
Have you tried to contact Jim Mattison or JohnZ? They may be able to shed some light on the COPO documentation since they were witness to some of the activities. JohnZ posts on TeamCamaro and the Corvette Forum sites. Here is a recent post of JohnZ's on a COPO thread.
"Zone Sales Managers had nothing whatsoever to do with COPO's or product promotion - their job was to make sure sales targets were met and cars were distributed/allocated to dealers to keep their inventories in line with demand - to "move the iron".
All COPO activities were managed from Detroit, by Ed Barlow, Jim Mattison and Joe Pike in Sales and Marketing, and by Vince Piggins in Product Promotion Engineering.

There was no shortage of cars to be modified at Chevrolet, whatever the purpose, without going to the trouble of ordering them and having to wait for them to be built; Chevrolet Engineering had over 1,300 cars in their fleet (including mine), and there were several thousand more in the Sales/Marketing/Public Relations fleet.

Inidvidual dealers occasionally modified their own cars for local community activities to create their own marketing opportunities, but all COPO activities and Product Promotion "special cars" were handled from Detroit"
