Guess I am not understanding; version?? They are stock/factory OEM injector bodies... I didnt buy them directly through DDP, rather I bought them through a retailer, so no, I didnt discuss it with anybody. Should I be looking for something here? I guess I thought when I asked for 50 hp DDP nozzles for a STOCK 2005 CTD with NO injector upgrades, I would've received the nozzles to fit. Are there different bodies for 2005 YM? What am I missing here? (i. e. bosch or other manufacturer; was there a contract change that year??) Throw me a bone!
