This is the Dart 2.0 Upgrade Kit. It will upgrade a Dart 1.0 to 2.0. It comes with everything you see here.
NOTE: If you don't already own short collar heavy duty pivot balls, you should consider getting some some. The float bridge on the Dart 2.0 is lower than 1.0. You can run the new float bridge higher using your old Dart 1.0 stand standoff/spacers and long pivot balls if you wish. But it will lower your CG if you use the short collar heavy duty pivot balls and shorter Dart 2.0 spacers (9/32").
