there's no need for the tray stiffner on the 2.0 and it wont fit anyways...all you have to do to use the 2.0 tray in the truggy is modify the dirt guard....possibly shave a mm or 2 off the chassy or Shim the servo UP...and of corse the linkages being longer you have to re-rig your 1.0's or buy the 2.0 linkages.
