I would agree with Tom M's advise that this could well be a driveline
problem.  Try pushing in the clutch and coasting at the speed where the
vibration is bad.  If it's the flywheel, it should go away right away, if
it's the dirvelines, it'll continue until you slow down and get out of
the critical speed range.  If it's the drivelines, then you might pull
the front shaft and see if the problem continues, then the rear (after
replacing the front). The manual transmission should be no different than
you auto for vibration.

If no one offers you one, drop me another line and I can probably locate
one (any color preference?).

Owner's Manual says either Mineral Gear Oil, SAE 90 or 140 or Engine Oil,
SAE 30 or 50.  Fill hole for the T/C is on the back (Dana 300) about 3/4
of the way to the top, square plug.  There should be two wires to the BU
light switch which is on the top left rear corner of the T-19 which is a
normally open switch completing the circuit when in reverse.   With the
auto, there was a third wire in the same connector that controlled a
relay that interrupted the start circuit.  You need different connectors
to connect to the T-19 switch.
