Hey all. Iím picking up a used 2wd rustler and the tires all the way around are pretty worn. Now I have googled a bit but only threads I found are about using front wheels all the way around. My question is this.... does the 2wd rustler use hex adapters in the front or is it old school with bearings in the front rims. This will help me in grabbing some new wheels later this week. Thank you
