I have a 1950 4100 with a 235 and a 4-speed and what I believe is an Eaton H072 axle, however I am not sure. What axles were in use in these trucks and what are the available gear ratios? Mine is 6.17, I checked it. I have located a 2-speed axle from a heavier 6000 series truck that appears to be very similar. I am wondering will the 2-speed third member out of that axle bolt into my axle housing and work.
