I'm trying to convert my '85 E350 van to manual steering. The power steering gear box had problems and I thought this would make a simpler more reliable system. The van is used primarily on the highway. I bought a gear box from the salvage yard that is supposed to be interchangeable with the vans; it came out of a ford ranger. The box mounts into the factory spot and hooks into the steering shaft.
The problem is that the manual box has a smaller diameter shaft to hook into the pitman arm. Thus my original arm doesn't fit. The ranger pitman arm is smaller.
What suggestions do you guys have? I was planning on dropping off both pitman arms at the salvage yard and seeing if they have one that matches the geometry of the original but will mate with the manual gear box.
