Steve, are you saying the new RPM ones are smaller than they should be or the Tamiya ones are smaller than they should be ?
I thought RPM were machining the new idlers not moulding, so i presume the moulded Tamiya ones are theoretically too small and RPM have made their machined ones slightly bigger which you are trying out ?
Sorry, just trying to clarify your statement
