Which boss kit fits a 91 CB GSR? I have tried the 2 that SAAS list as possible fitments (13-BK172L LANCER - GALANT 1989 - 1992 and 13-BK172BL CA - CB UP TO 1994) that were identical despite having different part numbers. Problem I had with them is they wouldn't go down as far as needed. They were both about an inch further out then needed so the horn ring didn't contact the pin which means it couldn't contact the indicator off ring. Does anyone know which one works with my car?
