I just got off the phone with Alcan myself and it turns out you need to buy their springs to get the orbit eyes. The eye in the spring is larget than the stock spring and you can't use them.
I was all ready to order them, but I want to go 4 link soon and can't see spending that kind of money just for a couple months.
I think the swivle plates are going to be the way to go for me.
