Thanks Gene, Amazon says it will be here on Tuesday so doesn't look like it will be an issue.
The bigger problem for me at the moment is I put a dial indicator on the harmonic drive output hub and used LCNC to spin the A axis. I then radially measured 0.0015" deflection and same with the face which also had 0.0015" change over one rev. Maybe it's dirty inside or has been reassembled poorly. But that's a lot of runout I would think.
