My problem: I've got a perfectly restored Tuff Wheel to go in my Charger. I've got the perfectly restored adapter that came from the same 1981 Mirada to go with it. That adapter does not work. I've also got what I was told was a "truck" adapter that seems to go onto the shaft but instead of a contact disc on the rear, has what I can best describe as a thick wire that terminates with an inward angle. This doesn't seem right for the B-body column.

What I am looking to find out: is there a particular part number for the 1971-74 (...79?) B-body adapter? Does the truck adapter work or need modification, or do I need to buy another adapter?

Thanks for the help.
