Paul,
   Seems that nothing is ever quite as simple as one would wish.
   Last spring, the wobble in the distrib shaft was so great that dwell
was swinging +/- 5 degrees off the specified 60 degrees.  I ordered a new
bushing.  New bushing was tapered on the outside and tapered on the
inside, so my machinist felt that it would be better to not use the new
one (need a $40 piece of bronze?) but to remove, invert and reinstall the
old one. Which he did.  Wobble was gone.  5,000 miles later, the dwell is
swinging +/- 2 degrees. Installing the Pertronix before cold weather set
in seemed reasonable, and simple.  
   There are those who accuse me of an unreasonable dislike of things
electronic.  Why that should be so, I can't imagine.  But then I've never
had wind-up windows, or manual sunroof, or hand-operated tire pump, or a
pull-string doorbell go bad on me.   What I may need is a hydraulic
ignition system.
Bob
