Alright. I got my 75hp injectors from my buddy. Here is the problem. He is pretty sure one box is the 75 and the other are the stockers but he just wants me to make sure. Anyone know that stock part number for a 99 cummins 3500 injector? I think the stockers end is a 629 and the 75hp end in a 635. I called DPP and they said the aftermarket should have 8 holes and the stockers only have 7. Well the both have 7. Ifsomeone can tlel me the stock injector number for a 1999 Cummins 3500 that would be awesome. ill try to look it up..

thanks guys
