Quick update / review of the U-box relocation brackets for '97-06 TJs (post #29 above).
The brackets themselves are very sturdy. To mount the bracket to the Jeep you have to re-use your factory screws from the pillar, so in my case they are red. It's minor, but I may pant it at some point. The kit comes with hardware to mount the mirror to the bracket.
As far as installation, it's very straightforward and doesn't take long. I spent more time adjusting the mirrors.
You do lose about 1/2 of the passenger mirror with the door on. This is partially because I'm fairly short (5'6"). A taller person is going to have the seat further back, and I'm betting you would have a better view of the passenger mirror. Driver side is fine. I'll have to give this a thorough road test to see if visibility is a deal breaker or not.
Looks-wise they are fine and the design doesn't scratch the hinges. Also, on the driver side the door doesn't hit the mirror with the factory strap. On the passenger side however, I had to tilt the mirror in so I could see it, and it does bump at full swing. If you are taller maybe you can adjust the mirror back one click, so it won't hit.
These are likely to be better than the pair of temporary mirrors I had, those just sat far too low to use with doors.
