Broken clip on A-Pillar mount

[96whgsx]

Well, I broke the clip that is on the a-pillar dual gauge pod/mount. The clip lost its head and the shank is lost inside the frame. Does anybody know where I can buy this clip? I bought the car with it already installed and I don't know what to do about this. The clip looks like a small screw that you just push in without twisting at all.

Here is a pic that was taken from wishingforagsx's gallery showing what I need.

ya can always just drill a hole and screw it on.
those plastic retainers can normaly be found at a automotive paint supply store.
