I've fitted my X-Nuts!
Greased up the socket, bolt and blue collar, took out one of the winch bumper bolts and put this in and tightened it up. A little difficult to get the socket out, but I think it was more to do with the suction of the grease, so used a pair of mole grips to gently wiggle it out. After it came out it was quite easy to put back in to remove it again. Also fitted one to the winch on the underside of the bumper.
Who else has fitted there's?!
