Need some help with the cowl ventilator on '49 Plymouth. So my cowl ventilator rods were not connected. Connected them with a 1/4-20 bolt and lock washer. Gave it a push and the whole upper ventilator went straight up and flopped over towards the hood. Looking up under the dash I see two 90 degree angled brackets with an empty hole in the free end. On the back of the ventilator are two keyhole slots. I'm guessing I am missing some kind of links that go between the two angled brackets and the two keyhole slots that would allow the ventilator to pivot rather than go straight up. If someone could advise what I am missing, it would be greatly appreciated.
Tech Sheets: while I used the Search function of this forum to see if any information was available concerning the cowl ventilator I stumbled on a forum entry from January of 2007 titled "Exploded Diagram Body Sheets" . These sheets show exploded views of body panels, doors, frames, etc. also the cowl ventilator . At that time they cost the forum member $9.99 from Ebay. If you click on the link at the bottom of that forum entry these tech sheets are now FREE.
