Thanks to both of you for the the photos. I looked at my dash and can see a small hole where a screw apparent goes through the other end of the bracket that goes to the dash. Is it a screw or a bolt? Any chance you know what size if I find a bracket without the screw? My radio has nut under it still.
I used a sheet metal screw. It was pretty small, but I don't remember what size. If you have the under dash AC vents it'll be harder to get the screw in than if you don't. Without AC you can just reach under the dash with a screwdriver.
