Sorry Paul,
I typed before I researched. I looked in my 48-52 Chevy Truck Shop Manual and saw in the Lubrication Diagram for the 1/2 ton the crossmember under the tail of the trans drawn in. Nothing in the trans section or any of the photos shows a rear trans mount or support, or any provisions on the trans case. My own personal experience is limited to a 50 3/4-ton with 4 speed, and it has no crossmember there or any rear trans support. Good luck!
