I see you are looking to switch over p/s to your truck, I believe the column is the same length. The manual box has an extension to take up the space of the power unit, That is how my 72 was set up. Mine was a D200 3/4 ton. Got every thing off of a salvage truck, it was a1/2 ton ram charger, everything fit perfect. I kept the same manual column, and got a new rag joint. Salvage yard told the same thing, to change the column But! before I get yelled at, my truck was a 4 spd on the floor, the ram charger was an auto. Double check the measurements on the column first with another truck. Hope it helps.
