...if you are resurrecting this, and it has significant wear on the chain, there's a possibility that one or more of those Uniglide cogs is worn, and the new chain you install will skip. I don't know of a reliable source for Uniglide cogs, but sometimes you can get lucky at a bike co-op, if it turns out to be a problem. There are instructions on the Sheldon Browne page for replacing those freehubs with something that uses Hyperglide clusters.
