Sorry, it's NLA. And, it requires removal of almost all components on the front of the engine (in particular, the fan bearing bracket) in order to replace it. Should be able to get a used one for sale.
Bad news is, the tube is ONLY used on the W124+M119, and the R129 with M119 with LH-SFI only (1993-95 USA model years). All other M119's are different.
How is yours distorted?
