I picked up these mirror relocation brackets from Amazon a few years ago. Makes it much nicer if you have the doors off all the time to be able to still have mirrors. I keep mine on all the time and just move the mirror back on the right door as it's hard to see it otherwise.
Nice Jeep!
Brackets That attach to the window. They are nice and solid. no need to remove them when the doors go back on. also easy enough to change back and forth as desired.
You could buy relocation brackets. On the passenger side on a JK they are pretty much out of sight but if you take the doors off often they're nice to have.
I have the Rugged Ridge Relocation Brackets.

Is what I bought and use on my JK Sport. Work just fine and a few bucks cheaper
