[Oh How Original]

Just wondering if there is any kind of metric conversion around for the SC10, to change the stub axles to a metric thread?
Being different sizes front and rear and also different in size to my others is frustrating, silly idea by Associated to make it all different.
I shall be changing over to a hex set up for some grippier tyres on the rear soon, so figured I'd do this at the same time, but I can't find anything that might fit.
