[W126 Coupe] Anyone know good used source for 380SEC vacuum pump?

[Bruce Mendel]

I actually found a good used pump at www.adsitco.com for $135, so I went for
it.

But thanks for the idea, I think I'll take the bad one apart once I install
the new one, and try to rebuild it for if/when this happens next time!
