Are they from the DF02 buggies? They look like it. I use them in my TT02B and just needed the diff housing from the DF02 and the outdrives, dogbones etc all worked fine with them. I just had to file down the diff pinion gear which was easy to do. Its a really common upgrade for the TT02B with brushless motors.
I don't know the part numbers without searching, but the Gravel Hound and Plasma Edge were models on the DF02 chassis.
