I had an idea to make one that bolted up to where the tow hooks mount but never did it.

 

If you go into onelow1ton's build thread I believe that he has a good example of one. I plan on doing one as well. But if you look through some of the build threads of the lifted guys with winch bumpers you can usually get an idea of how they did theirs.

Do you have a brush guard?
I was thinking of welding one of these in place of the current brush guard cross member.
