can try looking up denso part number nozzles for each engine and see if they match up. Amayama would also list which nozzle holders fit which engines, both holders would be unavailable.
Somehow, I doubt they are totally compatible , different eras, even if they did work to a degree, diesel injection is a fine tolerance. Watch how a nozzle needle slides down it's hole, it is such a fine machining tolerance, amazing really.
Once I purchased the wrong nozzles put in the correct holders of an
ebay exchange. My 2h engine bucked like a bronco. Won't do that again.
After much research, truly can recommend finding a diesel specialist you like and just pay them every 100k kms, at the very least for rebuilding your injectors. It requires clean, calibrated equipment not worth to own for an individual engine.
