i designed this chassis for a scx10/wraith transmission and axial ar60 axles you could probably use what ever you want. hell clodbuster axles might work with this chassis. also the body mounts use the little extra body posts from a scx10. all of the hardware is m3, i cant remember the lengths of the screws. i recommend going to teamknk's website and order a m3 monster bag. i used 130mm shocks off of a hpi crawler king, i believe the smt10 shocks are the same length but they leak a lot more. if you have any questions leave a comment i'm not on the site alot so it might take me a bit to get back to you.
