Use the national hot line to find the part at a traditional wrecker. They will ship it mail order. There are 15 or so wrecking yards selling the air pump, so maybe one of them pulled the bracket with it. Phone numbers are listed. http://car-part.com

Or self-service yards. Currently there are 210s in wrecking yards in Washington, Oregon, Utah, Nevada, and one in California. But they are self-serve, so unless you can go an look they won't look for the part by phone (won't tell you if that part is still there). The one in California may be gone by now since they tend to keep cars only a few weeks.
