are you going to run a 6 or 8? find you a good running donor car or truck for motor and trans, wiring, tilt column... your truck already has a 9" ford in it stock so put some disc brakes off a mid 70's ford truck on your stock axle. toyota 4x4 ( pre 86' solid axle) power steering boxes are a easy swap. keep asking questions as these era trucks are rapidly gaining popularity(57-60) nothing wrong with stock running gear either.the sky is the limit!
