I can't find an official part number for this, but I've guessed these are what I need:
http://www.ebay.com/itm/SET-of-4-Dodge-1500-Dakota-Durango-Hubcap-Center-Cap-96-97-98-99-00-01-02-03-04-/251499582591?pt=Motors_Car_Truck_Parts_Accessories&hash=item3a8e8b147f
I have a 2003 1500, with the 17" wheels. Any confirmation on the part number? Unfortunately, it looks like Dodge quit making these center caps, so used is my only option. But I do like these. It's almost the same price, but it's damn hard to find out what fits.

I actually need 3 of them, so I might as well buy a 4 pack.

On the subject, I'd really like to have a working ashtray (aka coin cup). Mine broke shortly after buying the truck, and just falls off if you open it. I found a part number once, but lost the page for it.

EDIT: Ok, I should make sure I'm being clear. The parts catalog gives this part number: 52110398AA. This, however, might look really weird with my wheels. This is only a minor issue as the rest of my truck is so rusty, you won't even notice that it has wheels. I thought I'd save a few bucks, and just buy a used set that matches the old wheels, but I can't find what part number was on it.

Thanks.

 

my 03/17 inch alum rims takes 52013653-AA

 

Thanks, I appreciate that. That's the part number I visually picked, so I'll just order a few of the used ones. Maybe I'll pop out the one I have left and see if those black ones are the same size

I also think I found an ash tray. Most of the part numbers from my PDF seem out of date. I'm guessing I need to reference something like an 06 or 07 truck.
