2004 chevy trailblazer_lt
I got a rear view mirror off of Ebay since I didn't have one when I bought the vehicle. No set screw in it so it vibrates to beat hell which is annoying more than anything. Anyone have any idea what size screw goes up in there? I am sure I could take the mirror off and head in side Menards but I might feel a little weird! Any help would be great!
