Clonk is stopped, no doubt the other side will clonk in due course unless the bushing has been replaced previously....and that is unlikely. I had to undo the drop link to ARB. I Didn`t undo the exhaust or rear mount. We are only talking about getting 5 mm +, more space to allow the top half of the bracket ( after splitting ) to raise above the ARB flange. The bracket split apart relatively easily, wasn`t riveted but a tight press fit . Hammering ( gently ) a screwdriver between the top and bottom parts of the bracket at the press fit end , with the bolts still fitted but loose , popped it apart. I gave it a rub with a file around the press fit parts so it would pull together easily on reassembly, it did.
