John were these used on most makes in this era?
From what I have seen, these were used mostly on Chrysler products, but in looking around I think they were on CJ-2 and early CJ-3 Jeeps too, but I'm not 100% sure.
They were made by Autolite. Chrysler used a lot of Autolite stuff back then, starters, generators, spark plugs etc.
