Recently ordered two directly from Monaco. They had them in stock. For under $ 2.00 each I also ordered and received two peel and stick stickers for the hub cap centers.
I have been amazed at how competent and kind the Monaco parts department has been. We have owned our Beaver since last June, and have been pleased every time we have called Monaco for anything. Follow through has been outstanding. As an owner of an other than Beaver from a major manufacturer, we have enjoyed a positive experience by comparison.
Good luck.
