Also remember that the 3 and 4 speeds have differant brake pedal and master cylinder linkage setups. You will need to carry over the correct setup. That may not work from 1/2 ton to 3/4 ton. Check under the floor boards and see. On one setup the master cylinder sits in a bracket that hangs from the bell housing. On the other the MC is mounted to the frame and is actuated by some rods and a bell crank that mounts behind the master cylinder.

Good luck with the truck.
