The blue truck was for Hubert Platt ( rip) and Randy Payne, The white truck was for Ed Terry (rip) and Dick Wood. the Shelby T/A cars for '69 were hauled in Semi trailers. Bud Moore did use COE ramp trucks but not this style. They were a "wedge" style , not a "dove tail" design.
It is possible the two trucks were repainted and one was given to Dick Loehr and the other to the Polaris Drag team . John Vermeersch would probably know. The "usual " giveaway is the originals used "disc" style Budd wheels and copies usually have "Rockwell" style rims that bolt onto a five spoke hub like Scott's truck.
Beautiful truck Scott!
