Steering column connector

Not much help here. I've never seen "in print" any replacement terminals for those connectors. I would find a different "better" connector and replace it. If you are concerned with "restore" appearance, only thing I can think is to contact one of the outfits making "original type" replacement harnesses.

Otherwise, you may be able to find some close/ similar connector terminals, and if nothing else, epoxy them into the old connector shells after termination.

Several high-current connectors in these old girls were weak points regardless of aftermarket add-ons, but adding more load sure cannot help!!

Don't forget that two of those wires carry the entire load of ALL switched accessories in the car, heater, AC, wipers, etc etc.
