As was the practice, there were several made that year that all shared the same color combination (white with blue interior) and which all had the lettering applied. They probably all didn't get the same engines (some may have been 383 4 bbl, some may have been 383 2 bbl, and some may have been 318 polys), and after the event they would have been dispersed among the dealers in the area to be sold. Most were only used for the parades. In this picture, notice the handles mounted on top of the rear quarter panels next to the top boot. I have only ever seen one 65 Indy Pace Car 65 Sport Fury with these handles (years ago at the Mopar Nats). I am assuming they were attached to only the cars that would have had someone sitting on the folded convertible boot at speeds faster than cars used in the parade would have seen. I wonder how many of the Indy Pace Car Furys had these handles. Would it have only been the car that actually paced the race?
