I needed a cover for my 9100 series..look on the inside of the forward arm. My sticker was on the inside of the lower arm, standing in front of the arm looking rearward the info you need is on that sticker. Then, use all that info on the web site find your parts..there are drawings in the detail for each major component that you can "pop open" by clicking on the assembly number on the left of the list...their customer service reps I've dealt with are pretty good at helping you make sure you get the correct stuff. I talked to them while looking at the screen so I made sure they knew what I was looking for...
