I have got the GGR diff mount as said it is made out of one piece of billet but I Had to adapt the upper bush bolt because it was hitting the ARB on mine, Motorsport developments one looks of equal quality with the added advantage of having the flush mounted bolts to solve this problem, I also fitted a 2wd Vibe-Tech gearbox mount on mine and some of Stu's Collins Engine mounts, all the above are the best mod I have done on it so far it vastly improves how the car feels.
