The 67 - 72 3/4 ton rears with automatic have a rear end that had 4:10 gears in them. They look just like the early 50's 3/4 tons, same bolt pattern, has bolts/nuts on both sides. I would have to look but I believe there are 10 bolts on each side. It is removable there may be others that bolt up directly to it but the 4:56 and 5:14 or something like that are the other gears found in the 50,s 3/4 tons. Not sure if they came out with the 4:56 rears in 67 -72 3/4 ton rears with that bolt pattern. If you have the 4:10 and deside to change your rear let me know I would be intrested in the pumpkin, Good luck
