Are you sure you have the correct parts or description?
The "Drip Rails" are on the edge of the roof, above the windows... There should be no holes. The ALUMINUM drip moldings snap over the steel drip rails that are part of the roof....
Are you referring to the "window guides" or "fuzzies"? These attach to the door and quarter panel, both inside and out, on each side of the side glass opening...
The chrome should face away from the glass, with a small thin flat rubber piece too... There should be "clips" that snap into those "peanut" holes, and also a few smaller (tiny) screws near the ends...
Depending on the year of your Chevelle (for your '69?), the inner fuzzies may attach to the door panel (68-72), or directly to the metal door (64-67)...
I forget, but I think the "fuzzy" guides go on the interior side, and the plain rubber go on the exterior side of the glass...
