IMO there is not a lot of the stock suspension stuff worth keeping. If you have to have a straight axle, I would recomend a new one with a nice four bar set up and vega cross steer, or maybe the new Uni-steer rack. If it were mine, it would be an IFS front and a 9" Ford rear with a triangulated 4 bar. Looks good, rides good, handles good, and good resale....
