What else would I need tochange my Earthquake 8e to aBackdraft 8e other than wheels,17 mm hubs, body posts? They are very simalar right? as well as the Aftershock 8e. I was thinking of doing this beacause while this truck is a blast I think that the tires are just to much for the diff gears so I want to change up and make it last and be a bit more stable.
