When I try to find the exact winch mount for my 2013 550 Grizzly and go thru the select charts thay have on sites that have many different mounts I can not find my model listed. The paper work I have on it says it is a YFM5FGPDR . Do I only look for the YFM5G when selecting my model ? I think the R is for red but no idea what the PD is. When I go thru the selection process on those sites it says part will not fit on my machine. Thanks
