When you get the tail assembly re-installed into the tranny case, replace the shift forks in their respective locations and re-install the cover plate. GV supplies the gaskets for the job. Although this image doesn't show it, replacing the output housing assembly into the case is a trying task. You must place the reverser gear at its mid-travel point and lower the Third- and Fourth-clutch sleeve half the distance of its travel in order to get the assembly started into the housing. After that, you must get the gears to align, and, when everything slides together, hope the needle bearings haven't fallen out of place.
