Not much help in the Shop Manual: Drive Gear - Step 17; Driven Gear - Step 19

It would be nice to see information from someone what has actually done this. I have a NOS pair of gears for use in a 1/2 ton with 6.50x16" wheels but have never figure out how/where to install the Drive Gear for use in a 1/2 ton with enclosed drive-shaft (in the transmission or on the u-joint yoke).
