He would need to machine new lower injector bodies to fit the new thread pitch.

I thought the problem would be more in the prechamber? In the om60x don't they sit at and angle in relation to the engine? Looked for an image in the W124 fsm without much luck.

The angle is in the collar. Problem is the swirl engines use different thread lines as well so the injectors aren't a straight swap like the prechamber.

the PC aren't straight swap either.
One thing is to cut/unscrew them and combine a lower part 617a with the upper part of an 60x somehow.
Don't know about the outer diameter but it is doable.

The 602/603 we are talking about with the angled prechambers are only found in the 1989+ W140 and 300D 2.5 models (in the US).

In 1989, Mercedes-Benz presents revised engines which cut particulate emissions by around 40 percent. Their features include a new pre-chamber with oblique fuel injection, which enables more efficient combustion. The diesel technology improvement program under which these engines are developed is called the "Diesel '89" initiative.
Also, I made a mistake; the updated injectors screw into the prechambers instead of the collars.
