Anything is possible.
I've swapped rear springs to the front. It is not a easy thing to do. You have to make the shackles about 1 inch longer. and move the front spring hangers forward, and with moveing the hangers forward, you have to fab up a new mount for the radiator support. Also, swap around leafs in the spring pack to get the ride height right.
On the plus side; it was free and it flexes like mad. I have some more things to get done so I'm not sure how it rides yet.
I think if I was to do it again I would probably do what "donoven" did with the wagonnere springs. Sounds like it needed less mods to make it work. (do a search for "custom springs", or go into my bio, and down on the lower side of the bio, you can go into "check all users posts", scroll back until you see "custom spring"
