,First of all,what are you trying too do? Widening the wheel length? <--->,If you are? Don`t bother going down too you`r hobby store and buying the over priced spaces!,Just use the normal Hexi wheel spacer you have,With some metal washers on top of the Hexi spacer,Get em from your hardware store! Dos the same thing..And dos not damage the wheel or the Hexi wheel spacer,And you can add more or less too adjust too how you like it.
