Not sure which terminal you refer to when you say spade but it sounds like something was replaced incorrectly before you got the car.

What we call spade in my industry is two prongs with a space of whatever stud size between so one doesn't have to remove the nut or screw as you would a ring but it fits exactly same.

If the spade you refer to is flat, and approx 1/4 in wide with a small slot that is pushed on a tab, then that is a more modern type we call a blade and never used by Packard to my knowledge.

They did use a push on that we call bullet type today which is round and approx 1/8 diameter but it would still fit on a stud (brake lite switch as example).

If you had a push on blade type before, then I think someone put an aftermarket sender on and maybe not the correct one for your car and might be why you're replacing it.
