My home made winch mount. The stock bumper is boxed as well as reinforced along the front. The mounting points are reinforced and larger bolts used (7/16" UNF grade 8, stock is M10). I also lost the captive nut and put in normal nuts by holesawing access from below. The mount itself is bolted to the bumper with 1/2" grade 8 bolts and to the front cross member with 3/4" grade 8 bolts. The cross member had crush tubes weled in. The bolting was sized for a safety factor of 5:1
The whole mess was galvanized. It has worked well. The only failing is that I should have reinforced the ends of the bumper as well.
