1991 Dakota 318 TBI Belt Tensioner made of Unobtainium

I found a post on here of all places where @66plyValiant showed how he deleted the air pump on his '91 Dakota. 1991 dodge dakota v8 smog pump removal tips

Unfortunately (for me), he used the existing tensioner and only used the Magnum pulley. I am ok with deleting my air pump, but I need to do it so I can run a Magnum tensioner I can still buy and I don't have a functional tensioner that would do what he did.

But maybe it will give some more visuals to what I am looking for.

BTW, it appears that the Dakota was the only TBI motor to get a serpentine belt and need this tensioner. All other models or engines had enough room at the time to run a traditional v-belt style accessory drive.

So, ragtopfury, since you have a 360, I can assume it came out of a full size truck or similar, and probably doesn't have a tensioner, or it is a Magnum. Be great if you could still take a look, but I'm not holding much hope that it will work. Appreciate the offer though.
