I believe that will fir the Pro 2 version without issues probably- just compare the part numbers on the center diff unit, partulallyllyylyyyly the brace thingies either side of the CD itself. After that, all you'll need is a battery tray really, and work out your esc location.

The 2nd link seems to suggest that at most, all you will need to do is swap the plastic CD mount thingy from a truggy to buggy version or viceversa, couple £ at most really (along with the other conversion parts).
