Update*** I am upgrading the clevis pins to 5/8" hitch pins this weekend, and I decided to take Billy's advice and get some bolt through D-ring shackles. By autocad, the weakest point will be about 20K lbs at the welds on the tubing. The front portion of the frame will bend before the bumper does, assuming the welds are good.
For the metal work guys, the inner tube is 8gauge, and the outer tube is 12 gauge.
I will post up the pics of the new shackle mounts, that may be a few months, but the pins are this weekend for sure, as well as some of the sheet metal work. I got my LED turn signals in, and picking up the driving lights Friday. HID kit for those will be in August sometime. I may not do the whole front end in sheet metal, it is starting to grow on me Just do the bottom and sides so it looks a little tighter, and a front facia for the lights and to hide the tubing. I don't know what to do next I am running out of projects. Any ideas? I may get the hubs this weekend too if it isn't 100 degrees and raining.
