TT-02 (base platform)
TT-02D (drift spec): includes oil shocks and full ball bearings, which are simply the most relevant "upgrades" to your question.
Variations in price within the above group specs are typically related to the licencing associated with the included body.

All the other variations of TT-02 platform do not include a body.

Are you planning on using the machine thread screws in the existing self-tapper threaded holes?
