used the $5 dollar bike mirror from canadian tire and I use the convex 2" mirrors on my HVAC vents. works perfectly and no blind spots. and if u dont wanna look at the mirrors anymore, just flip em around. cost total- under 10 bucks for everything.

 

We put a convex mirror on the passenger side one to help with blind spot.

 

I purchased DieTech Offroad mirror brackets (70 bucks + shipping+broker fees came out to 110) ... very happy

 

I don't have pics of my setup, but I bought these Universal Custom Motorcycle Mirrors - Free Adapters motorcycle mirrors for $12 and with a nut as a spacer, I removed the bolt on the A pillar near the visor on each side and screwed them right into that. Perfect bend on the mirrors arm! They fold right up against the pillar when the doors are on so no need to remove them. (The only caveat, is that I had to buy an extra universal hardware kit because the bolts that are the correct size for our jeep is a Yamaha thread, which for some reason is reverse thread on one. Meaning when I went to screw these in, one side wouldn't thread into the jeep)
It's a pretty awesome setup though. I'll take a pic and post.

 

Definitely gotta give us some pics. Myself I'd likely not buy a 2nd kit for passenger side as all I need
is a mirror on myside, but hey I'm way out in the boondocks where the roads are only one horse wide anyway. You big city boys can get run down from every direction!
So far the Harley mirror in the door hinge has done the trick.

 

I've seen where using the hinge with a CTC bicycle mirror costs under $5. works very well.

 

There are a few ways to get around the problem of not being able to see your reflection in a door with UTV Mirrors. One solution is to purchase a doorless mirror with a reflective surface on one side. These mirrors are available at most home improvement stores. Another solution is to place a small regular mirror on the doorless mirror. This will give you a reflection, but it will be a bit distorted. Finally, you can hang a doorless mirror on the wall and use another mirror to see your reflection. This is the best solution if you have the space. Whichever solution you choose, make sure that the doorless mirror is securely attached to the wall so that it doesn't fall and break
