Steering Box Question

HI,I know you probably get tired of this question,but here goes.In the past I have always built fenderless cars using reversed corvair box which sat on frame with arm down and they worked great.
My current project will have fenders.*I want to Run Side Steering with a Used Manual Steering Box Under Frame With Pitman Arm Up* .I have heard that a 1968-69 mustang box is the only one that will work,but there must be other boxes ,pickups,etc?.What are other boxes that will work?I have searched the site and still I am not sure of my options.thanks

 

Mustang 64 up to?? Falcon same era. 37-48 Ford car P/U to 47 ,same deal rotate 90* and there you are. The old Ford has the same type internals as a 'Stang [worm&roller] and is a fair amount smaller.

 

HI,Thanks for the information. I just put it down on paper so I won`t forget.Is that all the boxes that will work?Anyone know of any more boxes that will work? thanks

 

I'm running a corvair mounted upside down, with the arm pointed up. Mounted under the frame.

 

A lot of people used to use '60s Ford Econoline van or Dodge A-100 van boxes. I just gave a guy a Dodge A-100 box that is going on his '21 Studebaker roadster. He was glad to get it as it looks like it will solve his problem; I was glad to get it out of my way because I had stubbed my toe on it one time too many in my little crowded garage.
