I just rebuilt my drive train and used the pins for the wheel hexes, just cut them down to size with a dremel set up with a cutoff wheel. You can get them in the Losi drive pin set or you can even use some of your old pins if they are in fairly good shape. On the ft dogbones i left them long (stick out of the drive) it doesn't hit anything, it even might help out if it decides to walk out some(which happened to me a few weeks back) on the rears I did cut them to size 'cause it comes too close to the diff housing when the suspension is fully compressed, on the ft and rear center dogbones I cut'em to size using an old center diff outdrive as a guide so they don't stick out too far and hit the brake rotors. It takes very little work and saves a few bucks.
