I finally put together a price for the reproduction winch guards. They are made from a special ductile iron known as "semi steel " due to its toughness (but holes are still easily drilled in it for mounting specifically to your bumper. I did not make them out of steel as the pattern is even more difficult to make and due to the large number of risers needed the castings would have been even more expensive. The price is $ 584 plus shipping . I have two left right now.
specs for ductile iron ASTM A536 alloy GR 60-40 18
tensile strength 60,000
yield strength 40,000
Elongation ( ductility) 18% highest of the ductile alloys
