Adjusting the bumper alignment is actually fairly straightforward if you have ever taken the bumper off. Referring to the photo of the bumper carrier in LPMM's post above (the picture showing the carrier in the red rectangle), you can adjust alignment using a washer or two on the topside of each vertical carrier tube and angle-grind the same thickness off the bottom of each tube. Then slide the bumper back, tighten the 2 long T50 bolts and check alignment. If neccesary repeat using more/ thicker washers. A mm or two will make a big difference to the alignment of the bumper. The hitch I installed had angle-iron carriers so I wasn't able to re-use the plastic inserts from the original round ones. The inserts just act as spacers to prevent play between the T50 bolts and the carrier tube. Getting this right isn't too bad with a helper but it looks so much better.
