I know this thread is old but I am really sizing up this project now. So all I would have to do is swap out the 70's axle hangers and bolt them on the 59 frame and then bolt up the axles? Also how hard would it be to put the axles and/or pretty much the whole suspension from a 1995 F350 under the 59 frame? I just want a lifted 59 with more modern heavy duty suspension.
