Great underhood shots 60-66!
The closest thing to going back to the GMC dealership showroom in 1966.Priceless. This is an excellent reference for pursists like myself. Underhood shots are consistant with trucks built at the Pontiac Michigan assembly plant. It appears firewalls were painted fawn along with interiors, then the exterior color is oversprayed on top half of firewall only. I found a shot of a similar very low mileage GMC with the same Pontiac paint application, this case light green. Nice shot also of the "Custom" emblems with the original red and white stripes. The paint is usually worn off most trucks left out in the elements.Another thing that is amazing is finding such a pristine vehicle with such a long list of "hard to find" options. To top that off, GMC's are 6 times harder to find than Chevys in any condition. You have a terrific collection of gems. 60-66.
