the person who says it will be this much says its b/c i have to buy the whole injector b/c the truck has about 60k miles. if i just bought the nozzles could i install them myself? the place i plan on purchasing them from is called: srdieselconcepts.com and it says that it comes with the tool to pull the nozzles. i am just worried about making sure they are seated correctly and the pressures are right.That's way to much. And yep, you can get the nozzles and keep your bodies. :thumbsup
