The chevy truck box will work rear steer by moving the pitman arm 180 degrees on the shaft. It is likely the same box used on the Scout.The pitman arm on a Saginaw box can be installed every 90 degrees, as there are 4 blind splines 90 degrees apart.
13/16" shaft was generally used until 1978, after that the shaft was reduced to 3/4".
As far as I know all the 800 boxes have the same pitman shaft spline, except the 4x4 boxes in 73 to 87 trucks.
