Hmm...I will have to ask my boss if we got those, because we don't have any laying around that I see. I was told that if we get someone asking, sell the Est bindings, that's what they were designed for. If there is a plate, I must find it now, but as is, I usually get people to go along and just buy the original board. In my opinion, the more things you have to attach to the board, the more things that can fail and go wrong. I appologize and was going off the way I was taught which I'm finding out now is incorrect. If I had my digital I would take a picture of the boards we have sitting out, none have that attachment.
