[MRCA] Need BC-348 Mech Part

[D. Platt]

I'm in need of a small mechanical part for a BC-348.  Specifically, I 
need one each bushing nut for one of the shaft bushings used on the 
lower hole of each handle.  Someone, apparently, thought they needed to 
disassemble the shaft bushing to get the locking shaft out and lost one 
of the nuts.  I'd like to find one and can exchange some BC-312/342 
parts, perhaps?  Any BC-348 junk/parts or Hangar Queens out there?   
FYI, he threads are 5/16x32.
