Here is the only picture I could find from my installation. I lost the hard drive on my notebook and don't have access to those pictures right now.
The cradle itself is not limited on width. The width is determined by the frame members of the truck and are just over 24".
The bumper part that you see from the outside is an overlay or veneer. It provides no structural support, so what you see in the picture below is the strength and what you would be mounting to. You could make the necessary cuts or holes in the metal bumper to accomodate different controls.
The opening in the top of the bumper to view the drum is 9.5" wide X 3.5" deep. From the bottom of the cradle mounting to the inside of the top of the bumper overlay is 7", so the winch can be roughly 7" tall.
If the milemarker is 10" tall and over 24" wide, it would be a tough fit without cutting the top away more from frame member to frame member and exposing all of the winch instead of just the drum as with the Warn setup.
