During the installation of the EZ brackets, one side went on with no problem. When I went to do the other side, the rear post was a bit difficult to get in. When I tried to install the bracket, it would not align. Upon inspection, I noticed that the post was angled upwards.
OK, remove the post and have a look. What I found was that the rear fender bracket and the sissy bar bracket holes were not properly aligned. Thus the post was beign forced to be angled upward.
Tried a few different things but the solution was to take out the trusty Dremel and ground the Fender support bracket hole to align with the hole in the sissy bar bracket. It wasn't much, probably 1/8" on the bottom part of the hole. I placed a thick piece of cardboard between the fender and fender bracket as a "stop" to prevent the Dremel from going in too deep and damaging the fender or fender threads. Installed the post (much easier to install without the side load). The post was now straight and the bracket went straight on.
