I would like to put some apes on my bike like maybe 12 or 14 inches. I have a 2007 custom and already have a pair of stock classic risers for the job. Am I correct that I want the non-dimpled kind or does it matter? Also, if I need to change cables what tools are required? I'm going to be doing this myself, so any tips or help would be greatly appreciated! Thanx in advance for any help.
