Thanks for diving in on this. I wish I had mine done yet, but life... How did you mark where to drill the pilot hole? Some recommend putting grease on the end of the stud and mocking up the bumper to leave a grease dot. Doing it a few times before first drilling is obviously recommended, haha.
Anyways, looks great! Were you able to adjust the stud length to get the bumper to sit exactly as flush as you wanted? Looks like it in the pics.
