"So I need a replacement steer. I have gone with just getting a new CSU because getting someone to replace my current one will be a nightmare."
If you switch CSU with a different lower you may need to resize the bushings to suite the stanchions, or if its a little sloppy change the bushings in the lower depending.
Just as a wrap up the guy in New Mexico installed a new steering tube. Installed the fork on the bike and rode it. Had to rebuild the shock that was "like new" from sunshine cycles.
The fork has lots of new internals and works fine. Should have just bought a new one instead the junk ones in the classifieds.
