I have several vintage photos that were taken on race weekend at Indy in '69. Not a Polyglas tire on a Pace Car in sight...but a few are definitely identifiable as having wore small lettered Firestone Wide Ovals. (Not to be confused with the large lettered "Wide O Oval" lettering introduced for '70) Perhaps that's what the shipper sheet is referencing on that ZL-1 and COPO. Could have also been Firestone Sport Car 200s...does anyone know if they were they fiberglas belted?
