1991 Dakota 318 TBI Belt Tensioner made of Unobtainium

So do you need the whole tensioner, or just the pulley that froze up?

I put a new pulley on mine a short time ago. It is the tensioner that is froze, doesn't rotate any longer to put any tension on the belt. So, need the whole tensioner.

Wish I just needed a pulley, they can still be bought new.
