IMO, the bumper bracket to frame attachment point could be made stronger by incorperating both the stock hitch and bumper attachment points. you also need to have a better joint between the brackets and the bumper itself. weld it? maybe 4 grade8 bolts per side?
maybe the "in progress" pics are misleading....

First off thank you for the feedback. It's my error about the grade 5 bolts. I went to lowes intending to buy grade 8, but I had a brain fart. When I got home I thought "Damn it", all well I'll get the grade 8's when I install it premanently.
I decided to mount the bumper onto brackets for easier assembly. I completely understand what you are saying and I'm going to look into it further. In the long run I'd like it make it so that the bolts aren't taking the downward load, but instead just holding the bumper in place, if that makes sense.
I'll get back to you guys...

I don't have the time to type the steps right now, but I roughly calculated a safety factor of 13.8 for a tongue weight of 6000 lb. The force needed to shear the grade 8 bolts is 80,000 lb. I made the decision to use four bolts because if you take a look at the bracket mounts, four bolts due most of the supporting.
I'll post how I got those numbers later, I have class in a few minutes.

I got the shackles mounted. I cut a slot out of the bumper, inserted the mounts and welded the front and back of it.
Right now the primer is drying and it should be painted by tonight. Look for the mounted pics hopefully tomorrow(monday) night.

Thanks for bringing those up. I didn't make the mounts, I purchased them from www.rokmen.com.
For the amount of money to buy the steel bar, I could of bought the mounts from them......so obviously I bought them from rokmen.

Ok it's on. I got home late so I finished mounting it in the dark......so this is the best pic I could get:
lol, horrible ain't it.
I'll get nice pics tomorrow. I could have done a little better in smoothing the edges but it looks good enough to me. Lastly, tomorrow I need to drop by Autozone and pick up some electrical connectors to wire up the license plate lights.
I must say.......even in the dark this thing looks like it has *****.

EDIT: Oh, and the pipes did rattle. For a quick fix I stuffed some rubber between the pipes and bumper.....I'll make it nicer later.

Finally here are some nice day pics.
The thing weighs 76 pounds, which isn't too bad. Overall it came out pretty nice. I really like the look of a big beefy bumper.
Now that the rear is out of the way, hopefully I can get my front bumper under way in the next few weeks.

EDIT: oh and I think I want some bigger shackles. Those are 5/8, I can go up to 3/4 with the mounts I got.
