Parts...
 

Hello,

kit spur is 83t.
Since the latest kits have been equipped with the improved outdrives you will just need the medium flex front wishbones and an extra servo saver (kimbrough should fit, tamiya standard does as well!)
and yes, the hex wheel adapters are included in the kit.
hope this helps a bit.

best regards from Germany,
Chris
