Positive offset 12mm hex wheels JRXT options?

I have used the aluminum front Tamiya ones I posted on a basher before and they held up to a lot of abuse. Whether they are proper or not I don't know but worked. I seem to recall having them on the front of an RC10 too with the metric bearings, they were close enough for what I was doing. I'll have to order another set as they seem to have been eaten by my closet.
