1) You could call Carefree. I found them very helpful the few times I called. The telephone number I found is (303) 469-3324. The Carefree Web site is "broken" at the moment. When it's up, you cant put the serial number in their parts finder and the result will list links to parts.
Here's a link to that Web page.
2) The Stone Vos folks are great, and often can help you over the phone. You'll want the serial number and/or model number in hand before you call them. Their Web pages start
here, and include their phone number.
