Hi, parts stores will not carry parts like that,it is a dealer or specialty part. I don't have any information on dealers in your area,but have information on a company that does sell these parts, see the downloads that follow. Before you replace the part,I would make sure it is the problem,see if it is loose or out of place on the tailshaft or is physically damaged. Hope this helps you,Jerry.
