Yeah....I noticed that when I was looking at pictures of other front tube bumpers. Not all the Toyota's have them. I was a little thrown when I went to pull my stock bumper off and found those mounts. I didn't hesitate to take advantage of it though.

Those frame mounts really aren't all that beefy though, They are just 1/8" steel. I considered strengthening them with 1/4" steel plate, bent to wrap around the front, side and back and then welded to the frame (as well as the mount). But, I figured that was overkill.

While I was building the thing, I got to thinking about just how strong I wanted it......Years ago a freind of mine made a front bumper for his Chevy S-10 Blazer. He used a a 1/4" box section. The thing was mean looking....He used to brag that he'd hate to be the guy who ran into his truck.....Then someone did. Nothnig serious, guy basically rolled into him in a parking lot...maybe going 15 or 20mph. Caved in the front of the guys buick...really nasty damage, you could see an imprint of the box section on the front of the buick. We all laughed and laughed...then noticed my buddy's S-10 driving slightly sideway....it bent the frame!

Because of that, I intentionally bent the tubes that hold the bumper in place. They're pretty darn stiff...a lot more so than the stock bumper. But, I'm pretty sure if I tag a tree (or another car) the bumper will fold up. I'd much rather deal with body damage than frame damage.
