Hi Dave!
Yes, I did see what you're seeing there. My comment was a lack of sound deadening, not seam sealer, which is evident in the picture there. I may have muddied the water by just noting what I perceive as a lack of undercoating-type material anywhere under the car. This car just doesn't have much evidence of the guy with the spray schmutz getting anywhere near it. I will try and look at the insides of the quarters next time I'm down there and see what it has for the back and forth spray most Mustangs have. I knew Scott's website was based on Ford documents (at least one of which is shown on the site) and didn't doubt the accuracy. I would have to assume the x661 cars were just welded together and painted, ala the Galaxie lightweights. Besides being noisy as hell, these no dum-dum cars fared very poorly if they ever ended up as street cars since the corrosive water was allowed to run free throughout.
Now put down your carpenter tools and fly into Seattle one of these days
