Tested my wife's 92 300d 2.5 Turbo using my impulse counter made from an old bottle of ADD pills

, and found it had codes 5, and 15.
5 is the Vacuum Transducer, I don't remember what 15 was - I'll get to that later.
I tested the vacuum transducer - it is screwed, according to the FSM and it makes a noise so I am pretty sure it is a goner.
The question is - where am I supposed to get another from? Don't say Stealership, I am alergic. I couldn't find the part at Fastlane. Does it have some funky name or something, or is it generic and I can get another from somewhere else?
Help! The turbo's aren't working without it, the car is a dog!
Thanks.
