When I decided to use the 400 series box instead of the Saginaw it was partly do to the way the steering arm mounted. I did a lot of reading on steering geometry and bump steer, having the axis points on opposite ends only added to the issues. With the 400 box mounted in the factory location I didn't need to have the long steering shaft and double u-joints. I was also able to use the factory steering arm and an adjustable drag link, the factory drag link will work but mine was worn out.
Just a note: I have a 4 inch drop axel from Sid's.
