I have the Tomken mounting plate:
https://www.mcssl.com/store/tomken/tj-yj-lj-perm-winch-plate. It has gone up in price from when I bought mine (what hasn't?) and may be more than you want to spend, but it is seriously bulletproof, and you can save some money by getting it without the skinny little bull bar (calf bar, maybe?). It is a raised mount, about 2" higher than the top of the bumper, and fits most Warn winches, including the M8000. And yes, that is an OEM bumper, I just trimmed it down a bit.
