This is how I installed the BAK Revolver X4 onto my 2021 GMC Sierra with the CarbonPro box. Overall this method should work for nearly any tonneau cover so long as the rails have long flat edges that go along the bedrails. You don't need any special tools other than the handy drill jig that might make life a little easier. This was a fairly simple modification overall.
I found all the holes to drill by using a small pick between the bed rail cover and the box. You need to just locate the round hole adjacent to the square ones. If you pry back the plastic rail cover slightly you'll see it. Remember the rear most hole is already fully threaded and requires no U-Nut. You'll find the holes approximately 1-1/8" to 1-3/8" from the top of the rails down and from front of the truck to the back you'll find the holes if you measure along the inside of the rail from the front of the box:
1-1/4"
10-7/16"
26-3/8"
41-5/8"
54-5/8"
66-1/4"
You'll need to purchase U-nut's and flange bolts from Amazon

If you have a 3D printer you can download the drill jig file from here and print your own: https://www.thingiverse.com/thing:4708785
If you don't have a 3D printer but need the drill jig, send me $1 and I'll drop one in the mail to you: https://py.pl/1Cv9qV
If you have any questions or comments drop them in below and let me know.
