Went to put on a set of Wild 1's 515 (10") bars on my 02 Road King Classic and at first the clutch was too short, took all day but I located a clutch and picked it up. But now the idle and throttle are too short (about an inch). So I need a new extended throttle and idle cables. I have no idea what I am doing when it comes to getting new throttle and idle cables but I found the following numbers as possibly longer cables

38650-98 (throttle) / 56730-03 (idle)... does anyone know if these are truly the extended cables that I need? If not how do I go about getting longer cables quick. I was suppose to attend the last bike night of the season tomorrow with some bikes and go riding, but that's not happening now.
