does anyone have experience installing a roof rack. Question is; does the "screw plug" install from the top down, or from the inside of the cab to out. sorry for the bad pics. the brass screw inside is flush with the base of the "non flange" end. My thought process is from the top in, when you screw down the rack "legs" the brass plug will "bunch up" the rubber like a gyproc wall plug. The instructions pic suggests differently.


thx,

Al.
