Where to get enhanced replacement wheels for the Aristocraft Rogers 2-4-2?

My Rogers 2-4-2 saddle tank is the newer one that usually comes with a tender, and the one that has two motors and blackened wheels.

However this engine’s wheels are notorious for getting dirty quickly. girr.org says that Aristocraft used to supply enhanced replacement drive wheels for the 2-4-2T. How would I find those specific enhanced wheelsets mentioned?

I don’t want to accidentally buy normal replacement drivers again, and I ideally wouldn’t need to spend too much on two wheelsets either…

Thanks.

two motors? ahh that is right, it has 2 motor block “modules”’ inside, weird!

NOS (new old stock) drivers would be rare to find.

front driver part number is 21000–158 (each)
rear driver part number is 21000–160 (each)

part numbers did not change with improved materials
