Has anyone found a supply for the vacuum break on the quadrajet carb?

Mine has a defective diaphragm, there are no numbers on the break at all just a letter A and there is a number on the bracket but that is probably the bracket part number.

Thinking I might have to head to the wrecking yard with a hand vacuum pump and see if I can find a good one.

I've used this place to get parts for other jobs I've done.
(Including jets and kits). At least they claim the rubber parts are suitable for alcohol.

That's supposed to be Quadrajet Parts. Not "Quadrant"

Damn IPhone

Being a GMC repair shop, we carry all these parts in stock.
It is good to know that there are suppliers that specialize on these old
carburetors.
I'm never too old to learn from you guys as to alternate parts.
Thanks for sharing information.
So often we have stranded folks, and I will give them part # so they do not
need to pay overnight freight.
