If you seen the car and see the car again , just check the body #s on the rad support and trunk lip to the fender tag. That would save guessing on all the options
That will tell you that the Mule/Prototype body matches the fender tag. I assume it does. All the options that are shown on the Mule/Prototype show on the car today. No guessing there.
The guessing is trying to connect the Mule/Prototype to the Dec 1967 Sports Car Graphic Magazine test car. We don't know the Magazine Test car's fender tag. We do have a list printed in the article with alleged options on the "As-Tested" Magazine test car. At least two of those options listed in the "As-Tested" list were not installed on the Magazine test car looking at the pictures; the Wood Steering wheel and custom sill molding (rocker panel gills).
