[TR] carb link rod assembly parts

[nafzigerg at yahoo.com (Gary Nafziger)]

List,
I'm starting on the carb overhaul and wondering if there is a source smaller 
parts for the link rod assembly's.  I'm not sure what you call them but they're 
the little balls that are attached to the rod which insert into another rod.  
They look to be threaded and removable so I'm wondering if there is a source.  
Several of these balls are severely worn but the rods look very usable.
Just wondering.
