Hey Crius, just got my second G.I. Joe Willys Jeep. I took a few measurements if that will help. The centerline measurement from the front axel to the back axle is 12 1/4". The inside/inside dimension between the tires is 6 3/8". Let me know if you need anything else to figure out what running gear the jeep would need. rzingsheim referred to a king crawler that he used but didn't specify the model. I can send pictures too if that helps. Also, I would like to see how your friend is doing with his Dragon build and which forum that is.
