Hola from the 'Boro!
Sounds like a bearing to me, but I could be wrong. Hard to tell without actually looking at it. As far as pricing, you should give Sloan's a call. They usually have quite a bit of stuff in stock, and should have something like that available. If not they can have it within 3 business days. If it is a bearing, I hope you have a front stand or something soft to set the forks on while you're doing the work. Otherwise, it's gonna be a BEEEEOTCH.
Since I'm just down the road from ya if ya need a hand or wanna go riding sometime lemme know.
