Wherever John is getting his condenser I doubt it is from Ford or Autozone. I checked at both of those places and they gave me the 'what-planet-are-you-from' treatment. I think I did finally find a Ford dealer in OK who had an NOS one for $60 (plus $15 shipping) but I declined.
From the looks of the picture, John's appears to be a standard ignition condenser (capacitor to a EE) with a bullet connector on the side. Anyone could easily buy one of those except for the bullet. Also, beware, there is more than one size of those bullets and you need the one that fits the regulator plug.
An ignition condenser will sort of work except the capacitance is 1/2 what it should be which probably explains why they are usually about half size.

I couldn't find any that were truly the correct shape and all were quite undersized once I got them in my hands. A Farmall Cub tractor one looks correct except its made to about a 2/3 scale. I gave up and made one out of 30 year old NOS parts from Ford and Blaupunkt.
