Rear View Mirror w/ Roll Cage

Do any of you with roll bars/cages have a decent looking, non-obtrusive option for a rear view mirror?? I'm looking at some of the cage-mounted mirrors that are out there and they're all a little goofy looking. Most of them seem to be more for off-road rigs. I'd like to find something that has closer to a 60's car vibe. What do you guys use?? Thank you!!

No lectures on street driving with a cage please. :poke:
