I have a '75 F-250 SC - the 360 is getting pulled/scrapped, NO power steering. A 390 is getting pulled out of a '76 F-150, with power steering. While the 390 is getting rebuilt I'd like to swap the PS into the '75. The steering boxes and the steering wheel shafts are different lengths Can this swap be done OR what else is needed. + The '75 has a 4-speed & the '76 has/had an automatic.
