Anybody know where I can get a couple cowl plugs...

Not sure what they are called. 

You have to pull them to take the push rods out. 

The rubber grommet things up under the cowl. 

2004 2500 4*4

I would give Cummins or CPP a call and check prices. 

Wouldn't this be a dodge part? 

Find the Part number in the lookup tool

 

Under exterior panels, under plugs ~ page 888 and above

Yes.  But cpp sells a lot of engines and cummins has the parts as well.  

 

You can try dodge as well.   I bet dodge and cummins come in the highest.  If you want cheap, you could call the local engine builders as most i know seem to have 3rd gen motors being rebuilt or junked from washed cylinders.
