I'm replacing the vacuum line that goes from the booster to the intake manifold.

.

I need a new grommet right where the line goes into the booster.
It's the grommet where No. 6 plugs into in the diagram

ETK shows no part number; Both the stealer ande BMA tell me I'll have to find one from a wreck or buy a new booster. WTF? It's a rubber ring!!

Anyone have a suggestion as to where I can get this elusive part?

Thanks in advance.
