Hi Larry P,
Welcome to the Heartland Owners Forum and Family. We have a great bunch of people here with lots of information and all willing to share their knowledge when needed.
I think you should call Heartland Customer Service and ask for parts, 877-262-8032, or 574-262-8030. Have you VIN number handy and maybe they can help you locating one if they don't have any left overs. If you don't have any luck with Heartland, you can check out the RV Surplus stores in Elkhart and Goshen area.
Enjoy the forum.
