Researching 1967 Canadian Grand Prix Parade Cars

[1967]

This is my first post, so I hope I am not out of order asking a question right out of the box. I am researching the "parade" cars used in the 1967 Canadian Grand Prix. These were 1967 White Camaro convertibles with blue interiors. These cars were supposedly used as Pacecars and parade cars in other races in Canada in 1967. The cars are near clones to the 1967 Indianapolis 500 Pace Car. I am particularly looking for any copies of article or documents that would place the cars at different races, photos of the graphics on the sides of the cars, really just anything related to the cars and Canadian Races. Thanks in advance for any help someone may have...
