Thanks guys, I was trying to avoid buying the whole assembly, I thought just the plastic piece alone would be cheaper but I may not be able to find just that. The one in the link looks different than the one I have, the hole for the pin is more at the top than mine which is in the middle, not sure if that would work or not. I could take off the plastic foot cover and just use that I guess. Not much of a huge price difference between the one in the link Yogitunes posted and the actual whole assembly.
Thanks!
