Thanks again for the help. Ifound the 3racing diff and blades online. However, I am having trouble finding the nut. As you can see from the pictures a few posts back, the one that was in the car has a little metal nut that is pressure fitted into the plastic diff nut. The spare one didn't have a nut inside. On the one in the car the metal nut is round, while the spare plastic piece has a hex shape to accomodate a metal nut. can you buy the diff nut byitself or do you have to get a whole new kit?
Thanks!
