My mistake, the truck is a 1954 Chevy 3800. It does have an SM420 with an actual driveshaft with u joints, not a torque tube. I read one of the service manuals posted on here.

I was told the truck was uses by the fire department when it was new, I'm assuming by a fire chief or something, so it may have had turn signals or maybe some sort of switch mounted on the column or somewhere. I know there aren't any holes in the column drilled for wires to poke through.
