I had everything out when I switched over to LED's. When I reassembled it all my gauges had to be perfect too, lol. I figured an easy way to move it around until it was just right. As to the windex, it works wonders on things like this, next time you have to install a new set of grips try it out. It takes a bit to dry but when it does it's good as glued. It also works to uninstall them, just pinch up the end of the grip and squirt a bit in. With a little work it will make its way up the grip and the grip will slip right off.
