Well, not sure about this one, but I'll post what I know about my model and maybe the F3 would be the same.
There were some discussions on replacing swing arm, head, and wheel bearings recently in a VF newsgroup, and several people said, "Just pull an example of each, and head to a local bearing distributor/manufacturer, and they'll sell you the matches cheap." I've not heard refutation yet, so I expect that was a great solution.
So, I'd post this possibility to an F3 newsgroup and see what conventional wisdom comes back.
