I NEED WHEELS

Does anybody know of someone who makes good replacement wheels for the Aristo heavyweight passenger cars. I want them to be correct scale size for 1/29 (which I think is 1.24" in diameter). They should also have fairly fine flanges because I model indoors on code 197 rail.

Also, I need more MDC plastic wheels so if anybody out there has some to get rid of, let me know, please.
Remember, Model railroading is supposed to be fun!
