the broncoii you see in my avitar started off as a 5 speed 2.9, when i converted to the 5.0 i used a c-4, it was pretty sinple to convert from manual to auto, especially if you are getting one for free which will bolt up to your motor. all you will need to add off the top of my head would be a shifter, trans cooler and lines. something to keep in mind... i would leave the clutch pedal in place, since there is a clutch interlock switch, you have to either push in the clutch to start the truck or jump the switch out.
