Depending on your options, you'll have a few choices. The best thing to do would be to provide your VIN however, you can also look for your RPO code label, sometimes in the glovebox or in the driver's side door jamb on the door, and see if you have code "T72". This is for a car that was equipped with export options, which your car may very well have. There are only these two ways to be sure though. Also, do you need ALL of the capsule components? It looks like you can get part numbers for most of the parts seperately, if you could do that.
