Joe, I'm fairly confident that John made his comment 'tongue-in-cheek'. Finding the original WE spade lugs and appropriate tooling (I don't think that the hand tools for them stayed around very long) will be quite a task for such a minor operation.
Radio Shack used to sell crimps that were very small, but not quite as small. You could force them to do the job. I don't know if they are still available, except in perhaps a multi-pack. The key is the tangs inside the crimp barrel. Typical crimp terminals don't have these.
How about checking with Old Phone Co. in Galesville, WI? They've been around forever. They might have the complete replacement cord:
