I have already undertaken inspection under the dashboard with glove box and panel removed and if you could see what I and the wife (she's rebuilt the brakes and done other work on the car - she bought it in 1985 and is no wuss about working on the car) could see, you would likely discover that a digital camera is of little help in the existing circumstance. I already tried it. You may have a copy of the picture if you would like to ask me for it. Due to various angles and matters of negligible clearance, there is no way to see the point of attachment of the vacuum element's actuating arm to the flap until the element's rotational disengagement from its bracket is completed. I surmise that this step completed, a small mirror could be positioned in order to peer around the corner of the climate control housing which contains the flap and the point of attachment could then be spied.
