I would like to offer some advice: First, I would worry less about the length of the cables and more about the height of the handle bars that I need. If the driving force for changing the bar is the length of the cables, then the parts department at the Harley Store would be the best one to answer that. But I would worry about getting the right height of bars first, then the length of the cables next. Secondly, why do you want to change the height of the bars? If it is because of shoulder or wrist pain, you will need the height of the throttle about an inch or two above or below your shoulder. If you are for looks, then you will need to look at the bars and have a well stuffed billfold. Cheap handlbars will look cheap in about a year or two. (After they start to fade, chrome discoloring, rusting, etc.). So, what is the real reason for the bars?
