I am in need of a new steering cable but I got a problem. I can not read the serial number on the cable... Its all rubbed off and there is absolutely no way I can read it. I have a 2001 Tige 20i and I even emailed SKIDIM and they thought it could be either a 17' or a 15' but they aren't for sure which one. Anybody out there know which one i need????
