I got the dust seal ground down and everything put together and the cogs on the Sunrace cassette (that's supposed to be hyperglide compatible according to Sheldon Brown's chart) I got won't get tight with the locknut (unless they're supposed to be a little loose). Also the freehub body is binding up with the main wheel hub body shell so it probably needs another spacer or something on the bottom to free it up.

I may look into the RSX hub option mentioned above. Any particular one I need to look for?

I'm starting to wish I would've built this bike up with some type of vintage friction shifting group. This Shimano indexed crap is for the birds unless you can buy all the parts together that were intended to go together in the first place.

Being more of a Campy and French parts person I'm new to the Shimano world, and I'm starting to hate Shimano!
