Here is an ad for Castrol XLR featuring the 1969 Bud Moore Boss 302 Mustang of Parnelli Jones. As you can see, this ad appeared in June of 1969 but the picture appears to have been taken before the season started because the car doesn't have it's signature Boss 302 side stripes and all of the other advertising. It also features a side mounted gas filler. It looks to be the car Parnelli Jones drove in the Florida Citrus 250 NASCAR Grand Touring Race at Daytona International Speedway, Daytona, Florida on February 21, 1969.
