Can anyone help me lolcate this label? 617 engine

[Thomaspin]

The p/n is 123 584 49 26 - it's the black emissions label which is attached to the cross member in front of the radiator when the hood is opened. I had the misfortune to smudge mine with some solvent and I would like to replace it with a new one. The dealer told me it is no longer available.

Any help would be appreciated - this is for the 617.951 5 cyl turbodiesel in a 1983 300SD.
