Before you get in a hurry to get the cover have you confirmed the selector switch even works? Just cut temporary cover out of a cerial box and tape it in place and see if it works.
There are 4 ports:
Main Vacuum from manifold.
Hi range to rear.
Lo range to rear.
Small line to speedometer cable reduction unit mounted on the back of the speedometer.
I'll see if I have a bracket to take a picture of when I get home.
