I have two fairing well nuts if you need them. If you can get a needle nose pair of vise-grips around the well nut, collapse it down tight, then attempt to remove the screw???? might this work??? LocTite eats plastic, rubber, etc.....
When I installed my new lower fairings (2004 parts w/ 2-wellnut fasteners) I thought it would be better than my 2003 set-up which is one dzus fastener.....boy was I wrong.....so I went back to a dzus fastener. I just placed a piece of red duct tape over the fastener and seam to keep the fastener up there and the fairing together should the fastener fail somehow.....200 mph tape..

Let me know if you need the wellnuts and screws!
