If it is a Super and brown like this it should be a 1966 model. OliverNate....Ive heard that as well on the JDs about the ditch. Ive taken the steering units out of the 4020s before. G1355....If you can get the unit out there are a couple of places that might be able to do it. Didnt someone mention once on here about using a different steering motor from something else on them?
