Memphis Equipment. You might have to call them or email them, as they are not on the website, as far as I could see. $25 a piece, new!! And shipping for me to TX was $30 for two rims. Still cheaper than a not quite right aftermarket rim.
Thanks for the tip! One more reason to go back to Memphis. Cozy Corner BBQ, the Flying Fish, the Flying Saucer, now Memphis Equipment.
