I have two sets of installation instructions for installing a Bushtec hitch onto my R1150RT. Both are supplied by Bushtec. The first set of instructions was sent by email about 1 week ago and the second set came with the R1150RT hardware kit that I bought from them. The emailed instructions do not mention installing the 3 hole bracket or even list it in the parts list. It is as if it doesn't exist. The instructions that came with the hardware kit says to install the 3 hole bracket on the hitch hoop. Can someone tell me more about how to install this bracket? Is it necessary?
