Also what size ID do the bearings need to be for the KOP axles (long bolts if that makes more sense)? One last thing, for the sprockets mounted on the CIMpleboxes should we just order 2 more double KOP sprockets or 4 single slightly larger ones. Thanks!

You'll need 4 independent gearboxes for Mecanum wheels. The CIMpleboxes are pretty fast so you need a rather large sprocket reduction to go with them. This gets to be a bit of a complicated setup - with 4 CIMpleboxes and 4 sprockets, 4 chains to adjust, 4 Mecanum wheels to mount (not sure if you want live axle or dead axle.) If you read the various threads on Mecanum wheels, teams have had success direct mounting 6" Mecanum wheels to Toughbox Nano gearboxes (12.75:1 gives a pretty good speed.)
