Hey folks I'm new around here but recently installed dual dogs for a MS-361 on my 261. Everything went good except for the provided screws being too short for the dogs. Then I went to install my stihl chain catcher and it's about 1/4" too narrow. The width is 1 1/4" and between the dogs I need 1 1/2". I believe the part I installed was 1122-650-7700, and I believe I've seen there is also 1135-650-7700 which is 1 3/8" wide? And possibly an even wider one for the 880? Does anyone have any knowledge of the part numbers and width of this one? Or can point me in the right direction? Thank you very much!
