I did what you want to do but fabbed everything from scratch (or more correctly got people who know what they're doing to do it for me). A couple of pics below if it provides any inspiration. I went with double tubes on the front for more strength with the winch (fabbed the mount for that too) and stability when fitted with a rack or recovery gear box. On most trips the recovery gear box lives in the front receivers where it's all readily accessible, and the winch is stashed and protected in the back of the truck because it's hardly ever used.

The square aluminium plates fit in to more receiver tubes in the recovery gear box frame, and are held in place with standard hitch pins (as is the box frame itself). They get slipped out to provide front recovery points for a snatch strap, or a mount to put a front tow hitch for tricky trailer positioning. They also fit in the original receivers on the front around town, when there's no rack/box/winch, to leave no sharp leading edges. Like receiver mount plugs that some folk use out the back to dress up when no tow hitch is fitted.
