I have one from a working truck that I'd sell for $100 + shipping. I would recommend a rebuild of course, since it's an OEM carb. It has been sitting on a shelf for at least 1 year.
I have another that is 1 year old that was given to me by a friend. I would have to charge you too much to be worth your while, I was told it was $900 new from the dealer. That's going to be the carb on my next project.
You best course of action is to get your old one rebuilt by one of the recognized carb experts like JimC (fj40jim on this board) or Mark ALgazy at Mark's Offroad in Burbank. Both of those guys are in the neighborhood of $300 for a rebuild and worth every penny.
