I was installing a headlight flasher and took the plastic cover off my GT bars - the one that covers the brake resevoir next to the mirror stalk on the left side. It turns out that the screw was being held on by rubber cement - it was just glued on. So my unscrewing the screw tore up the rubber cement, and I ended up fabricating a little clip like was on the other side.
Seems kinda weird. Maybe my GT is a collector's item now? Or maybe it was assembled on a Friday afternoon?
Headlight flasher is fantastic, by the way. Cars are allergic to it.
