when putting the anti roll bar mounts back on, jack the anti roll bar up in the middle so you can line up the 2 brackets with the holes in the chassis,a lot easier that way.
oh, when taking the mounts off, undo a bit of each bolt at a time or it will be hard to get a socket on the other bolt, if you take one fully out,the arb will push the bracket down and you cannot get at it.
