looks like we got it figured out---
cummins doesn't sell just a headgasket yet for the '05--it comes in kit form and that threw him for a loop and upon initial request that didn't get translated, but a call to cross reference weeded it out--so I think it's all good to go--
sometimes when you play you need to be your own warranty station and in this case he needs too, so he can get it back running by early tomorrow---chris
