shifter fork screw

["Jack W. Drews" <vinttr4@geneseo.net>]

Does anyone have a good way to remove the little square head screws that
hold the shifter forks to the shifter rods?

I've tried vibration, light hammer blows, and heat on the rod, but have
not found a good way to do it, and even if the screws are drilled out,
new screws do not seem to be available in the U.S.
