Sources for Chrysler type wire terminals
Bought some Aptiva/Delphi/Packard terminals from Mouser.
These are not exactly the same as the original Chrysler terminals, but probably close enough to get you a cigar.
The two Packard terminals above are the ones with bright blue part numbers.
The terminal for 12 gage wire was out of stock or had a minimum of 50 to order.
Some Tin Plated terminals are still available.
The Aptiva drawing has the part number for no longer avialable terminals cross off. This includes silver plated versions.
Chrysler parts book listed silver plated terminals, which I had doubted were actually silver plated but rather described the color. Now I take that back.
