Also, the clear plastic gauge cover snaps into postion. On mine, once I laid the overlays down I couldn't snap the cover back on. In fact I had to cut some snaps off..
But, since the clear cover is held firmly in place on the dashboard by the screws holding the cluster in place it didn't matter.
Oh, if you do glue... make SURE YOU DON'T LET ANY GLUE TOUCH THE GAUGES OR NEEDLES. The needles are electric and take hardly any torque to turn. If the glue hits the needles and prevents them from moving you'll have to take it apart and undo the interference. I found that out the hard way!
