Doesn't seem to be much coming out of the coil.  In fact, I don't feel
ANYthing.  And since I'm gonna get a Pertronix with a new coil anyway,
I think I'll just wait til then.

Don't throw parts at it just yet.

If you don't have a spark at the coil wire:
Check the output at the coil wire as you short across the OPEN distributor
points with the key on.  A screwdriver tip is all that's necessary.  The spark
should occur as you remove the screwdriver tip -- not at the time you short the
points.

If you get a spark that way, clean and reset the points.
while cranking, if you get a spark at the coil wire and none at the plug wire,
the problem could be the distributor rotor. On the GT's the resistor carbon
piece on the rotor has been known to fail (open). You can usually see it. Also
inspect/replace the cap if necessary at this point.

If you have no spark at the coil wire then disconnect the condenser and try
again.  If this action restores spark replace the condenser. Do not go without
the condenser . The condenser is needed to prevent arcing at the points, an
undesirable thing.
 
Get back.

Try it with a hot wire from the battery directly to the + side of the
coil. If you see "spark" at the points when they break... your problem
is in the ignition circuit IE: switch, feed-wire from the solenoid,
ballast resisto, etc..., . Otherwise- it's "past that" IE the
points/condenser/coil etc...

Always suspect the CONDENSER!

Points that have been sitting unused for a long time can be covered
with oxides that prevent conduction, clean them with fine sandpaper or
a small file.
