Forgot something: Anyone ever try to buy the little spacers that go on the axles behind the wheel from Duratrax? AFAIK, you can't! Don't even have a part number!
But I found that Durango makes a replacement you can buy by itself. Team Durango part# TD310032 "Crunch Spacer, Front Axle (2pcs)" $2.79

Don't see them on Tower Hobbies, but you can get your LHS to order them, or, buy them from Amazon! (I am finding more and more RC stuff on Amazon)
