I have a part that has broken on my 1980 240D. I think its called the throttle linkage. It has a red "STOP" sticker on it, and connects to the throttle and pivots around a shaft. It has a rubber block connecting two metal pieces, on of which contains the "STOP" sticker. DOes anyone know what this part is called or the part no? I've searched Fastlane and Performance products for "Throttle" "throttle linkage" "shotoff" and a whole bunch of other terms. I've also seached for the numbers I see on the part (617 584 00 21 and 799215) and can't find a thing. Any tips on finding this part? Thank you.
