Instead of playing the back order game and waiting a month for $100 mirrors I went old school. For the wallet killing price of $7.50, two convex blind spot mirrors stuck to A/C vents. Did this in my JK's work's fine.
I literally have mine on only to keep me legal in case I get pulled over. I have the Carolina metal works ones. They look awesome but really aren’t functional anyway to me at least. I would never rely on them.
