Does anybody know if these Monark nozzles are for sure compatible with Bosch injector body stamped: KCA30S35/4 044 135bar

I just want to make sure I have the right ones. I have Monark: 329 39 305 120
Which are Bosch part number: 0SD 261
These are the nozzles that Mr Kent sent me from Washinton.

I can't find my injectors listed in the Monark catalogue. And all I can find is that these nozzles fit an injector used on the NA 200D 601 engine.

Ok my old nozzles were DN 0SD 240, and from what I've discovered is there are a whole bunch of different nozzle styles that would fit these nozzle holders. Also, that the 261 is perfectly compatible and an updated style that people have been using for a decade or more. The diesel mechanic (An older British man) said Monark is one of the best parts companies period. As 1 of only 2 certified Bosch diesel repair centres here in Toronto, I'll take his word.
