Actually I guess the proper term would be safety wired shut. I simply removed the element from the car, broke the element in half, re-installed the arm back into the flap and safety wired the arm to the "element bracket". This holds the flap shut so you cannot put your hand into that opening. In this position Only fresh air is allowed into the car.

I actually have found where to get the new diaphragm's to fix it. I have just been driving the car too much to mess with it right now. You can re-use the old elements and just replace the diaphragm's.
