Early Dodge/Fargo Power Wagon engine swap question

WOW!! Nice truck.
If you look closely you'll see that I made and installed heavy 10" channel iron to replace the original bumpers. This made the truck look very heavy duty. Each bumper weighed close to 100 lbs. When I was in Wyoming I drove through a snow storm (white out) and someone had left a VW bug in the middle of the street. I couldn't see more than 15/20 ft as I drove my way back home, I ended up cutting through the bug with the channel iron bumper. The VW was mangled and I couldn't find a scratch on the Power Wagon bumper. After I inspected all the VW carnage I looked around, I couldn't even see the houses on either side of the residential street (white out). So I got back in my truck and drove home
Did someone convert your truck to a duelly or did it come like that from the factory?? Your truck cab looks a lot like mine!! COOL TRUCK!!
