If you are referring to the the transmission brakets, there have been a few people that have reported it's not necessary, but I'm a big guy so I found it a lot easier to to take the extra steps to remove the battery tray.
Good deal, thanks for the update. I'm looking at doing the bushings at the same time as the short shift bracket. Wasn't sure I wanted the hassle of pulling my battery. Did it make a noticeable difference in shift slop to you?
