I liked that bumper too, (I think I drew that measurement sheet, I can't remember it's been awhile) either way those are the measurements of my bumper but it is a zr2 so it would stick out 2'' past each fender on a regular 4x4 s10.
It was literally my first time welding, and I did it with a $90 dollar Harbor freight flux core welder. I also used a $500 dollar plasma cutter, but I've also used a cheap angle grinder to cut the sections out it's just more dangerous. (I would use the thick cutters not the egg shell thin cutters slower but safer)
My zr2 flares are gone so you can see how much it sticks out.
