Hello Pieman, what kind of trouble. The rod connects to the vent on top and a lever, fulcrum thing under the dash, I think the rod is held in place by push on fasteners which you should be able to find at the local hardware store. There is a spring under the flap too, without the spring I anmigine it would just sort of flop around. I can all be a little fiddly to get in place properly.
