added to say i left the stands under the abr mounts until i had removed all the suspensin and undone all the stuff i wanted to undo
i then moved them to the chassis legs once i'd undone the arb mounts

but i also put a plank of wood between the stands and the chassis legs because they can be just a little slipperly

also added to say that i've got 4 stands so i used 2 either side, you can never be too carefull
