hate to break it to ya but...... Since you live on the lovely 'communist republic of commiefornia' as I like to call it, you are out of luck on converting that truck to a diesel. Unless you keep it registered out of state or in a non-smog state. If you haven't already changed registration to CA, do your conversion before you do. Because of it being a truck with a gas motor that is in smog years you will have problems with CA.
