I found my old order. Sep 2002, ordered through Glenmore Sailboats in Calgary. They're called Coaming Pads on the order, and were C$49 each at the time. I think I talked to the Hunter parts department to get all the part names and availability, then ordered it all through Glenmore Sailboats. It was a large order, including stern rail seats, a window, companionway door, shroud T-bolts, etc.
I see they have a store in Edmonton as well, and still mention Hunter on their website. That said, you might try ordering direct from Hunter. As Dave mentioned, I would probably look for plastic instead of teak. My friends H260 has plastic.
