"Clips" might be illustrated in the "Standard Parts" section of the parts manual, but probably are of the "insert" type which is placed in the hole and then the "pins" on the backside of the molding are inserted into them, to retain them. Personally, as those clips can chip the paint when they go in, I might opt to use some well-trimmed 3M molding tape to secure them instead. Might not be "correct", but would ensure "one more area" where rust might not happen in the future. PLUS easier to remove should the need be.
Perhaps the reason they did not install the smblems is the fragility of the pins (on the backside) was tested on a few of them?
Enjoy!
