That looks like the short shaft that goes between the tranny and the open driveshaft on a truck that's bigger than a 1/2 ton. I'm seeing a carrier bearing mount on the bottom end in your first picture. Here's a page from the 1941 Truck Info Kit showing the driveshaft info.
What size is your truck? A 3/4 ton would have the intermediate shaft just behind the transmission with another u-joint then either a torque tube or open driveshaft. I THINK there would indeed be a different arrangement for the oakie bushing, which would go back behind the carrier bearing

If you're smart enough to take it apart, you darn well better be smart enough to put it back together.
