It won't be cheap like something in a junkyard, but I bet you can find something if you go after-market. I think what you are looking for is primarily something the right width--depending on the track width of your truck, which may not be right with the stock MII sway.
Try Addco
http://www.addco.net/ or one of the chassis folks like Fatman's or Heidt's.
Of course you may get into fabbing the mounts a bit, but some adjustable end-links can make that pretty easy. Good luck, hope this helps.
