Here is what I came up with this weekend using 3.5X3.5 box steel .250 wall. I don't like cutting any stock brackets off the frame, and I figured the stock hangars are pretty strong, and I have some real beefy front crossmembers, a hidden winch mount, and a .250 wall 2x4 bumper to tie everything together. What do you guys think? I do plan on welding a tubing sleeve into it where the bolt goes through the stock spring hangar. The shackle angle ended up pretty good too.
