Look in the passenger and drivers side storage (Behind each seat). Maybe they were stuffed in there?
maybe you can double check your cars build-sheet? Try this link and add your vin. Yes, its says its for a RAM truck. But it works for me.
This cupholder is excellent IMHO. I drove a NB Miata for a long time and always considered placing some sort of strong and sturdy cupholder exactly where it is placed on the passenger side. Lots of spilled coffee in that vehicle. The engineering on these cupholders is well done, sturdy and removable. The center console one is installed only when needed, usually long trips with my sweetie. Note they are not interchangeable.
