I've been using this site for awhile. It shows factory parts diagrams along with part numbers, including superseded numbers. You can enter your VIN also.

 I've also found similar sites for ford and chevy that come in handy for side jobs.

 

Good find Mr. Turley...and thank you for sharing! 

We have the same thing here...

I saw that before. I think the website is a little easier to use. It updates superseded numbers, pricing, and if a part is discontinued.

For engine Parts, filters I either go to Cummins or Freightliner Just have your engine #

Filters, fluids and gaskets I've been using Amazon for awhile. They seem to beat most prices. I have a buddy at Cummins but i try not to bother him too much. I just use this place for part numbers never ordered anything from them.

I don't use Amazon for anything.
