Tuff Wheel Adaptor

There are Two adaptors for the Duster column I was told cause I have both...for some reason two different sizes...was told one was for column shifter columns and one for floor mounted shifter columns....don't know how true it is....but one does fit my old column shifter column and my other fits the one for the floor shifter column...

I can see year diff but I have two...and the price on these are going up and up....seen then at the nats in sad shape for 100.00 without the nuts...
