I just ordered a pair of these extenders. Once they come in and I get them mounted, I will let you all know what I think of them.I got the factory ones, which really leave a lot to be desired. They are up too high and the mirror can't tilt high enough to get a good view. I did find a set of these online. https://www.helibars.com/kubota/ Looks like exactly what I am looking for. Here is a video of them from the maker.
