Here’s a couple photos of when I was getting my 2022 model fitted up with the on the rox metal fender. There is a real amount of trimming to do. You’re not cutting beyond any pinch welds tho.
I am a fan. Is it worth the money? I can’t answer that, but I really like the extra clearance it gives for my suspension to travel, I like that the flare covers most of my tire, and though I have not tested it yet I am a lot less worried about running into something on the trails now
For reference, this is a 2022 with the climax long travel suspension kit, using 4 inch Rubicon express leaf springs and that is a 35 x 12 50 tire mounted on the factory wheel with a 2 inch spacer
