Your '70 uses points, a coil, and a condenser.  This SYSTEM cannot
work if the condenser is either shorted, or open.  I've had two
condensers fail open over the years, and lost spark both times.
Not a weak spark, but dead!  Never had a coil go bad.

Only if the fuel pump is still working... (that's another story).

You might want to check the point gap.  Without regular lubrication, the
rubbing block tends to wear down, causing the point gap to close up.
The car ends up barely running.  It will idle all day, but has no power.

If you want to learn how to do the diagnosing of your car, DON'T use the
shotgun approach.  ONLY CHANGE ONE THING AT A TIME, and TEST the result
as you do your work.  Makes life much easier next time you have a glitch
