I just bought a new oldstyle chrome arm and installed it. It has the scallop type look, real purty... I figured I'd put in a day/night mirror as this will be my daily driver but when the mirror arrived it has the threaded shaft that goes thru the arm with the bolt attaching on the end... the arm only takes a mirror that threads dirctely and not thru the arm... I haven't figured out what I'm going to do yet. The other problem I think I'm going to have is the new visors I installed my be too long and will hit the mirror.... nothing's easy.
