Good morning,
In my opinion buying used or cheap parts will just cause issues again down the road. I would advise going to the dealer first and getting the parts that came on the vehicle originally. 2003 is not that old. I have a 2001 Chevrolet Suburban and I get parts from them all the time. Especially hardware. I have worked in dealerships that served Dodge, Chevrolet, Ford, Kia, Hyundai, VW, Audi and Nissan. Nissan I can get parts for vehicles from the 80's.
Also, the serpentine belt area gets everything that goes through the grill thrown at it and runs your vehicle. Including salt, water and sand. So, you are going to want something tough. OEM parts are built to fit that exact vehicle and last a lot longer.
Why don't we try getting your VIN and I will see if the parts are available for you. If not, then I would definitely recommend trying Rock Auto, Advanced Auto Parts, O'Reilly's, or NAPA. I would use the junkyard as a last resort. So, in my opinion we should at least try the dealer first. At the very least we will have the Dodge part number which will make these parts much easier to find.
A lot of dealers put their obsolete inventory on eBay, with the part number you will be able to find them much easier. Dealers can also locate parts around the country at other dealers if they don't have them in their inventory and buy from them. It's called Dealer to Dealer.
In my experience the last thing you want to do is do the job again because you got a cheap or used part. This is my opinion.
I have also attached a diagram of your serpentine belt system for your reference.
Do it right. Do it once.
Thank you,
Brendon
