I have not watched any of his videos, but the Wing Cars were not finished on the line.
Noses & other mods were put on at Creative, so for one thing, it is totally normal for the Creative painted nose to not match the factory painted body very well.
Were the nose cones installed before painting ? I just can't figure out how things like a vacuum modulator behind the carb got overspray on them .
I guess since the Daytonas used '70 fenders and hood they were installed at Creative Industries as well which could explain all the overspray.
