Hi,
First timer on forum. Was wondering if anyone has had the Vacuum Pump (gm 55578091) fail and has found the part has been discontinued. I have paid twice for the part online and was later emailed they couldn't fill my order. Even the Temecula dealer noted the replacement part was discontinued. Any advice. Also have been searching ebay and looking at pick a part places.

GM parts online still is advertising the part but they were one of the sites later said they couldn't get the part.

European part number 704166060, not sure if you can import it from Europe.
Otherwise salvage yard.
