Smitty says:  I scribed a spiral groove the length of the inside of the
bushing with a tiny ball grinder in a Dremel tool.  Then scribed another
all the way around the center of the bushing inside.  With the metal
sleeve and nylon installed, I drilled through the end of the relay rod
and tapped for a Zerk fitting.  With the bolt installed grease comes into
the circular groove and encircles the bolt, intersects with the spiral
groove which feeds it both ways.  I have one in use installed 14 years
ago which still has rotational friction and no rust.
