No we did not use the versa blocks because we used a plate drive system this year. The construction was similar to the 2014 kitbot but with our own custom sideplates from 1/8in 6061 aluminum, live axles, and the 3 CIM VP Ball Shifters with mounting holes for the WCP line of gearboxes since we left ourselves open to try different gearboxes if we needed to.

All we used for mounting was 4 bolts that attach the 3rd stage to the main gearbox with the axle extending across to a bearing on the opposite plate.

The plate the gearbox mounts to has a cutout that allows the gearbox to be removed from the underside of the robot without having to slide the entire gearbox into the center of the robot (slide it out of the bearing on the far plate and it comes right out). The blue and red parts are just PVC spacers to keep the wheels and chains lined up. We color coded them blue (0.25in) and red (0.55in) so between two robots all spacers are the same and easy to identify. You can see the cutout I'm mentioning where the red spacer on the middle wheel meets the gearbox.
