Interesting...the color combo is really nice too!.
Somewhere I believe I still have some programs and/or brochures from the Edmonton Can-Am races...I don't remember the cars but I'll take a look and see what's there?.
Reading the seller's notes of the car that sold, it notes he had the GM Microfilm copy!.
As I've mentioned here before, these microfilm copies include 30 plus cars w/ options as equipped and are what GM Historical uses to prepare the magic documents...they've stopped including the microfilm w/ documentation packs in recent years but what I'm getting at is that the possibility is good the three (or more) cars would have been ordered together...if the cars were shipped out together too, they may all be included on this same microfilm...yes, Vins and all!
