Truck CalTracs on an A body?

There is a guy that comes in to the feed store I work at that has an 03 3/4 ton chevy. He has a set of CalTracs on it with his stock leaf springs. He said he does not want them he will give them to me.


So I was wanting to know if they will fit on my Duster. What would it take to make them work. I would think they would. May need to be shortend some do you think?
