Hi Ron,
  Yes, those caps are all intrinsically "straight" pull.

  The standard part from Jennings included the bell & screw drive
assembly.

  There are several custom variations wandering around which may or may
not accept the standard ¼" drive.  A lot of those have shown up on the
surplus market in the past couple of years... same thing happened in the
late 60's -- does it coincide with the sunspot cycle?

  Loose drives show up occasionally at hamfests, or on e-bay, but, they
are typically much rarer than the capacitors.
