I have a 77 Honda GL1000 Goldwing with a Windjammer SS fairing. I recently got a Vetter headlamp cover, but when I put it on the headlamp bucket it doesn't seem to be very secure (feels like it might fall off!!). Does the original headlamp bezel have to be in place for the cover to stay on? I currently have only the bucket (no rim, sealed beam or retaining rings) on my 77 gl1000. The inside edge of the rubber vetter cover has a ridge which looks like it's supposed to go into a crevice (like you might see as the joint between the bucket and the headlamp bezel. So... any experience on this thing out there? Thanks!
