Uh hey gang , new here but I have been in the repair and manufacturing business for years . I just aquired a 1978 Ford F-100. It has the standard Non assisted steering box. I also have a 1978 Ford Econoline E-150 with the Saganaw power steering box . What I would like to find out is are the two steering boxes interchangeable and how much is involved .
Om a second note if anyone ever has a Flat Head question , I am all to happy to try and offer advice and help. You can e-mail me at edshaver@ymail.com thanks Ed Shaver

 

I don't think they are interchangable due to the mounting direction and how the E series is mounted.
