Items to do the hex conversion:
ASC9880 - Team Associated Hex Steering Block Set
ASC9881 - Team Associated Hex Front Axle Set
ASC3977 - 3/16 x 3/8 normal wheel bearings (4 pcs)
ASC6943 - 8/32 wheel nuts (I like the JCI2076 or JCI2075)

12mm hex adapters
PRO6077-00 and PRO6076-00 or JCI2081 and JCI2091 or ASC7497 (plastic)

Hex front wheels
PRO2735-02, PRO2734-04 or ASC9690, ASC9691

Hex rear wheels
PRO2736-02, PRO2736-04 or TLR7100, TLR7101

I didnt list JConcepts wheels as they are not current in stock at Amain and I haven't personally messed with the Kyosho wheels... but they should fit.
