My truck had a long block installed under warranty and I no longer have the original ser. # to look up anything, just the ser. # for the long block. Can someone supply me a serial # for an 2006 so I can look up cummins parts.

 

Guys, I could really use a serial #. Just received my AFE exhaust manifold and would like to order the gaskets I need to install it. Cummins is no help without this.
