got an original press photo of it.
There were several shootings
Most pilot cars have litte "off" details which change till production.
Check out all 1970 Rallye wheel cars in the brochures. They don't have center caps.
Or the 1970 Super Bee/Coronet brochure. The red grill surrounding got deleted for final production as well as a chrome ring for the Ramcharger hood was added. Ever seen that the brochure for the 1970 Bees doesn't show the Super Bee emblem between the two bumpers they all got in production?
