[R-390] 390-A VFO Rebuilders?

[W Gladhart III]

Hello Group, I've been awarded the care of a Collins R-390A. It was received upside down with the VFO removed. The VFO shaft is stuck solid. I picked up a beater replacement from Fair mainly for a set of bearings(?) but I don't think I should attempt messing with it. Can anyone recommend someone that can repair and align this VFO so I can power the unit up and find what other surprises it holds in store?
Thanks,
