190d 2.5 turbo injector body question

It depends.. Is the prechamber retaining ring slotted (early) or does it have the internally splined retainer (later)? Early style injector threads into slotted collar threads at top of injector), later injector threads into prechamber(threads at bottom), not the splined retainer.
