I've been searching and searching for this stupid brake booster vacuum hose and I can't find it anywhere. Anyone know where I could find a discontinued part like this? I've already checked rock auto and eBay etc. Part number is 22723583. Car is an 06 chevy cobalt 2.2

 

Try calling the local dealer - even though the part is discontinued, they can check inventory at other dealers to see if any of them happen to have one in stock.
