May not be a simple question to answer. These guys http://www.radmfg.com/default.asp used to offer one, although looks like they're out of business. I did some research, and from what I found, it would appear the Cush drive wheel from a CCM GP450 could be made to work. I believe there are instances of the CCM guys using a Husky axle as an upgrade. As CCM is not yet available in Canada, I have not been able to confirm the sprocket/brake disk spacing, spacing through the hub, and spacer requirements to confirm this could work. ANYONE with a TE630 have access to a friend with a CCM450, or even a CCM dealer where you could make a few measurements?
