As far as I recall there are two or three different bushings. The differents is within the radius of the inner gap. Measure the inner gap and head of to the shop. I've the book you mentioned but its all writen in German. For me living in Holland that is no problem but I understand that the most people who live in the States don't read/understand German. If you have a question or so just leave a message. Greetings from Holland.
