Designed to fit 95+ GMT400 overhead consoles in the blank space where rear climate controls usually sit. The side radius isn't dead on, but I've spent too much time on this, and it's close enough. The second file is designed to fit the Retevis RA-87 faceplate. Can be attached to overhead console using screws no bigger than 3/8in or 10mm. I used a couple of self tapping screws that I found underneath someone's house.
