Nothing missing. 1960 to mid 1990 there was no standard colors on NASCAR race cars. Teams may even have different colors of chassis and details. Petty was more consistent color wise as they were the top team money wise of the era. It's pretty easy to google photos online of Petty cars. Most were Petty blue chassis, darker blue suspension. The other details can vary year to year or even race. Drive shaft is white on all cars of that era.....that was a rule. Rear diff was often red oxide, Lots of silver/aluminum. Like I said....google it! good luck
