I think with the light-duty you will probably be all right. If you were going to make the change you would need a set of shackles, shims, and lock plates. You would need to drill two holes in each frame rail and two holes in the cab floor right behind the seat pan on both sides. Then you would just remove your center shackle and bumpers. Here is a picture of the parts set-up.

Interestingly the set pictured is 1/2-ton only with offset holes on the frame all other trucks are inline.
