Are these the clips i need?

Upper door panel trim on 73+ uses screws. There is not a hole for the screw, but a slot to allow for adjustment.

Correct, all over these cars (my 67 Barracuda and my 69 Polara as well) there are slots like this for screws. Easier on production not having to hold the tolerances for a screw to hit a dimple on center.
