Need this to go away! The insert is plastic not glass, it appears that you would have to remove some screws from the back and open the unit to replace the face, not sure how it came out, screws don't look like they have been removed lately, this is the way I got it. Perhaps the face is from a different unit and the person was going to replace it in this unit, whatever, what you see is what you get, as is. Their is a rattle in the unit when I tip it from side to side, may be the needle from one of the gauges. odometer is at 127k or thereabouts. Got as a box of parts in a clearance garage sale. If anybody can use it I will take $10 for it plus shipping.
