Thanks for the replies. I had sent Thor an e-mail and their response was they do not sell parts to the public, try a dealer. Closest dealer is Camping World in Hamburg, NY. I called them and their response was they cannot look up part numbers, bring in the broken part and they will try to match it up. Not very helpful. I think I was disturbing their afternoon nap or something.
Next step was a brief search online with the part number but nothing relevant came up. So here I am asking you lot for direction. I will look into these suggestions. Thanks again.
