rear gear box runs in forward the front runs in reverse, all linked up. The Forw/Rev levers linked up would do the Forw/Rev as normal ( front Diff/Box runs reverse when rear Diff/Box is in forward) The Gear shift levers give drive to both boxes, having adjustment at each linkage connection is to fine tune the engagement points..
