Ack,
On the center of the tubular 'crossmember' part of the front frame, there is a little 'mount' of some kind, almost dead center. It looked like something slides in there. Well, I wasn't sure what it was for, and nothing was in it, so I also utilized this as a center mounting post.
I slid a piece of 1/4" steel into it, with a bolt hole on one end. I lined it up with the bracing on the backside of my bumper, and ran the bolt through it. It was sturdy as could be before, but it's gotta help some.
I still plan to run some longer bolts through the box frame, but don't need it yet.
I'm 22yrs old, welded my first hollow metal door frame at 15yrs old. I've got a lot of experience with light metal with a mig, and some arc welding...fun stuff! Now if only I could afford a TIG, this whole thing would be aluminum. Have you ever tried welding aluminum with a torch? Saw something on it the other day...never thought about it though.
