yes a manual ute tailshaft will work fine in a manual sedan

and just incase you dont already know, you will also need to either weld sedan diff mounts onto the ute diff or weld on shock mounts for use in a sedan
and the brake lines will also need to be swapped from the sedan diff onto the ute diff and a new splitter mount welded on
handbrake cable coming from the diff will also need to be shortened for the sedan
