On my 67 I hate how my mirrors never stay in the spot i put them in. I adjust them and after 5 minutes of driving they are all misaligned again. Not to mention they touch the cars paint when they move. We've all seen people add the modern car ones but what about if the paint and body are already done? Some modern styles the use the same mounting base? That would be cool. That should be easy for the guy that can make entire dashes from solid aluminium.
