I purchaced the Go Westy  luggage rack stainless steel screw set a year
ago. The screws were supposed to fit the top luggage rack, and rear hinge.
The heads,though large,where much smaller than the OEM screws. I called
them about it. They said that they used them fine. Well, I installed
them,and the first one cracked the fiberglass. The head on the rusty OEM
screw spreads the clamping force over a larger area. The new  GW stainless
steel screw concentrated this force in too small an area.This, with only
light pressure from the screw. Needless to say, I was pissed. I see a
market for correct westy screws, and infact all the exterior screws on the
Vanagon. I am attempting to gather the correct stainless steel screws for
the westy pop top. Lots of rust up there ,too. Thanks again,Roger
