A bit late to be of the help for the 18 car, but have you looked at this smugmug album? https://bigalsphotos.smugmug.com/search/?q=jarrett&c=photos#q=daytona&i=171
Not too late at all. Thanks for sending that along. It'll help with other cars, too. Very much appreciate this. It also confirms, as far as I can tell, that @Lastlap was correct about the contigs/order.
