My trans has a tab on the bottom of the tailhousing with two holes for the studs on the bracket to go through. The tab is pretty much centered in the middle of the housing underside, and the studs from the bracket could go in from either the pass or drivers side. Obviously, I need to mount the bracket from the drivers side for my slap stick set up, but then again, I can't imagine any trans linkage brackets being mounted on the passenger side.
