Yes, the chrome metal clip is just akward to manipulate while trying to hold the diaphragm in place. I thought maybe
there was a trick to the process but it looks like it might take an act of Houdini ;-)
I've scattered and fixed numerous regulators in the past myself but never had the bemusement of fighting
this battle. If the darn thing didn't breath so well when up and running, I'd probably give it to the dog
to chew on, but Im not quite at that point...yet!
Thanks for the reply!

I decided to try sliding it into the case and over the diaphragm through the right exhaust port while keeping it
in the upright position. since it (the retainer clip) has a tang on each end, it stayed in place while I moved it around
the circumference of the Diaphragm and it snapped into position. I doubt this would have been easily accomplished
had I not lubed the diaphragm first (lightly) with food grade lubricant. I had to stare at the thing for a bit before
deciding to tackle the task for fear of damaging the irreplaceable diaphragm.
It's still a good Primary second stage but probably rated rather low regarding ease of maintenance,
but then it's 35 years old so...
