Will the CVDs of the 501x fit, or do you need to get DF02 bones and then slap on some 501x axles to make things work?
Also, has anyone else using the stock dogbones on the DF-03 noticed that they squeak when articulated? At first I had thought I had done a terrible job on the AE shocks that I put on my DF-03

, but then tried articulating the suspension without the shocks installed and realized that the metal on metal contact of the dogbones in the outdrives and axles was causing a squeak.
