ultima 96inch motors

my father bought this motor over eight years ago. the motor is still running strong. my problem is, my front cylinder is cracked about three fins from the bottom. i have been looking for a dealer other then jireh. jireh told me that ultima had stopped making that motor. i can't find a set of jugs, anywhere. can someone give me a lead on this problem. i can run s&s all day long. but, the dickhead shops where i live won't help me out. just looking for a number or hell even a e-mail address will work. thanks
