The post bolts through the frame and the top winch must be removed and then the step over the winch is through bolted together. There is a collar that must slip down over the post on the install which is connected to the winch step. The drilling is through the double wall pivot tube, which is the toughest part. Not bad for us as drilling steel is a part of the job, though some have commented that it is hard, and itis the double wall tube that gives that impression. So you do have some drilling to do. BCB
