Replacement cones for Sansin hubs?

[JRobert]

I was given some free wheels (matrix rims,700c), and in the process of working on the rear decided that it needed new bearings and cones. The bearings were easy, the cones are not.

Is there a site that shows if there are replacement cones, or other newer cones that can be substituted?

I hate to see these nice wheels sitting around for lack of cones, and really don't want to buy new hubs to fix the problem, kinda like overkill since they will be just for riding on a trainer.

Thanks, JR
