The tub will need a waste and overflow, connected to a p-trap.
If there is no room on that side of the tub, you may need to plumb for other end.
Or, remove whatever pipe you need to reconfigure for the prefered location.
Those sections are installed using lead and oakum. It can be worked with. You can sometimes saw off a section and couple to it too. Most of the time, I'm removing a section and reusing the old hub.
