There has to be some type of torque tube ball housing support for 1953 and earlier manual transmission trucks with a torque tube (edited). The torque tube ball housing needs to fixed in place with the truck frame. Inside the ball housing, the inner ball swivels with the motion of the rear axle and the splined shaft coupling moves in-out direction also with the motion of the rear axle.
If you have an open driveshaft transmission/rear axle, you don't need the torque tube support if the rear engine mounts/support are capable (strong enough) to support the transmission weight. Being that the rear motor mount was improved in 1954, I would think 1953 and older trucks may benefit with a transmission support.

"Adding CFM to a truck will only help at engine speeds you don't want to use." "I found there was nothing to gain beyond 400 CFM."
