Actually, I had to cut the bumper to install the high-lift jack mount and d-rings bracket underneath. It's hard to see in the pic. The HR bumper won't need to be cut for the winch. It is a bolt on process.
The tight fit part.....well, is getting the two bottom inner nuts back on the bumper (8 in total). After the winch is installed there is hardly any room. It ain't easy, but it can be done. My only suggestion is to have someone around with skinny fingers, to get the nut started.
Good luck!
