Replacement Wiper Arm
pmmarkus,
i did the same thing on our 2015 Thor Axis. I called Thor and they replaced the arm complete with a new wiper blade at no cost. It's worth a try calling them. They will at least know which arm to send to you. Thor was very helpful. Getting the arm off of the gear will be the hardest part. I was so afraid that I would crack the windshield if I used too much leverage; so I used a fly wheel pulley. It worked like a charm.
