Prestolite made ignition products for both Ford and Chrysler, not just Chrysler Corp.
Prestolite/Autolite supplied electrical components for a lot of the "orphan cars" that didn't make the stuff in house. You'll also find a lot of Delco (GM) electrics in orphan cars.
Exactly the reason I haunt all the local Studebaker swap meets. There's gold in them there hills.....
Funny you mention that, I developed an electronic ignition conversion for the Studebaker Prestolite distributor using the guts from a SB Mopar aluminum electronic distributor. Amazing amount of interchangeability...weights, governor, breaker plate and even the vacuum advance are pretty near a drop-in interchange, just had to tweak the phasing of the reluctor to make it work.
