The trim that right inside the door thats about 2 ft long and has 4 or 5 screws that hold it down on the carpet. Its right next to the outsides of both seats. Not sure what it called but I need a new pair, both the passenger and drivers side is starting to crack, it would be great to have an aluminum one but the original plastic one would be great? Any aftermarket stuff or is this a dealer/junkyard item?

 

Junkyard is probably your best bet unless someone on here has a set?
