there is a spring that connects to the diff & the valve, it' adjusts rear bias when it's loaded/unloaded... i'm not that familiar with the rear of the GV's but i'm sure it would be to reposition the spring that's attached to the diff & the valve & i'm pretty sure not all parts in the calmini pics are shown.
i don't think i've got pics, but the 2 brackets go over the transfer case crossmember & the bash plate bolts to them & the single one goes over the tube crossmember BEHIND the transfercase & with the plate attached it clamps the crossmember... go outside & offer them up, should be pretty straight forward.
