I shone a flashlight into the opening around the arm and watched while slowly increasing the vacuum, the diaphragm pulls evenly throughout the stroke.

Interesting observation. Can't say it agrees with what I saw
Think if the short part of an "L" if the long part is slanted then
the short part also is. The short part is connected to a flat washer
on the other side of the rubber diaphragm. Since the washer is held
at the same angle as the crooked L then the rubber is not pulling
evenly all the way around.

The statement "the diaphragm pulls evenly through out the stroke" is an interesting conclusion. How did you determine this? Did you measure? I know my eyes are just not good enough to see a 1/16in deflection difference. If you release the long part of the L from the ball stud where does the straight part point? Is it still crooked? What would pull it back straight? The deformed rubber maybe? hmmmmm

Thanks for all the insight and suggestions.

I think I understand why you're making that decision.
Yes, it's bound to work out just fine for you.
