I'm not familiar with that model at all. but, on my 108, 1200, and 1450, there are bolts on the side of the frame towards the front (they look like frankenstein electrodes). That is where my mule gear slides on and "hooks" at. I have a slight gap between the hooks and the frame. you don't want it too sloppy cause of wear, vibration noise, etc, etc and you don't want it to tight due to the loss of "quick disconnect". IMO, I would say that the part that clips to the bolts is maybe warped or spread to far open. I hope this helps you some, but there will be someone else who is by far a lot smarter than me on this subject chime in. Jeff
