Another thing to consider is where the handle will come out. Photo is of an 8n. The TO starter bump out might interfere with the position of the handle. I know to install the step up/down in a ford NAA or later hundred series the handle come out to close to the bump out and the handle has to be altered to fit or ran out the other side of the tractor which I don't believe the redrock handle has the capability of doing. You might want to pop the steering box off and take some measurements before investing in the conversion. I have some 8n trannys with shermans in you need measurements for shifter.
