Been looking at afns hidden kit and came up with my own made from 10mm angle steel. Mounted the same as afn kit but welded on. I've ordered a proper winch plate from eBay so will get theses tidied up. Then save for the winch. Number plate maybe relocated yet
You thought about sticking a couple bolts to the chassis rails in as well? (Probably overkill but I know my winch bumper bolts onto the chassis at 6 different points :nenau)
:thumb2 good point.could always make the tray slightly deeper than the afn one so the winch sits further forward and gives a bit more clearance on the bumper.
