A few people are a bit unsure what parts are needed to do this, so I thought I'd create a new thread about it instead of going off topic in others
Parts needed for the B4/4.1
Steering blocks - AE part #9880

Axles - AE part #7496

Front hex - JConcepts part #2135

Rear hex - JConcepts part #2091

(You can also get AE part #7497 which will get you all 4 hex's in plastic)
Finally the wheels themselves, a choice of Proline or JConcepts...
Proline front - #2735-04 (white), #2735-02 (yellow)
Proline rear - #2736-04 (white), #2736-02 (yellow)
JConcepts front - #3347 (white or yellow)
JConcepts rear - #3348 (white or yellow)
The hex conversion gives you the same fitment and offset as the Kyosho RB5, so any wheels compatible with that car should fit, the TLR22 rear is the same too
B44 style front wheels won't fit on the front, the offset is wrong and the car will be much too narrow.
Parts needed for the SC10
Steering blocks - AE part #9880
http://www.teamassociated.com/parts/details/9880/
Axles - AE part #9881
http://www.teamassociated.com/parts/details/9881/
Front hex - JConcepts part #2134
http://www.jconcepts.net/store/index...roducts_id=537
Rear hex - JConcepts part #2081
http://www.jconcepts.net/store/index...roducts_id=470
Loads of SC hex wheels around with different offsets, the hex conversion makes the SC10 the same fitment and offset as the SC10 4x4 so any wheels that work for the 4wd will fit the converted 2wd
