Here is the bumper Travis Rankin made for my old 4Runner before he moved to the Mainland. it was incredibly beefy without being as bulky as an ARB or a Slee. It has a good amount of protection for the lights, radiator, and body corners. The expanded steel section was to protect the tranny and oil coolers while still allowing airflow. The front receiver was for a removable winch basket. On the Cruiser, that expanded steel/receiver section would be replaced with a winch plate for a permanently attached winch.
The only thing I didn't like about that bumper was that Travis used preformed angle sections, instead of custom bending the tube. You can't tell from the pics but the joins where the straight tube met the bends was a little cheesy-looking.
What we forgot to add was a licence plate mount. I had my front plate and commercial plate held on with zapstraps, which was lame.
What I did like what the great approach angle, the lack of coverage in front of the wheels, and the insanely unnecessary giant D rings

Also, the main horizontal section is 4" (just over 100mm) high, so I guess if what John says is true, then this bumper was technically up to code. Although, for reference, those were 33" tires, so I guess most of the bumper was far above 22" from the ground. Meh, I never had a problem from the good folks in blue.
Footnote: I love my Cruiser but I totally miss my 4Runner. I see it around town sometimes and I want to steal it - I even still have a key (not that one is needed).
