I would almost say it is the same on most of these motorhomes. If your smaller arm is missing it is a part of the larger arm and is 117769-01-000.
Thank you for the info. It gives me a place to start. The large arm is attached by a nut but not the smaller one. Somehow the shaft adapter is screwed into the underside of it. The small arms look like they should have spring like the large arms but they are missing on both sides. I might end up getting the adapter plates from the am equipment website along with new arms.
Still waiting on the key so I can open the hood and see what kind of wiper motor I have...lol..
