I have a broken pivot post it is the one that the wiper attaches to. This is on a 2007 journey. I called around looking for a replacement and can't find one. Winnebago does not offer an alternative. Does anyone have an idea where to get one or an alternative fix. The threaded part on the top broke off while removing wiper arm. My thought was to face off and drill and tap a hole. Not sure if it would be strong enough. Any suggestions
