I just run round bottom Rancho u-bolts on mine, 5/8"x3.25"x8.75" (p/n RS17436) and they work fine. Cut to length as needed, grind a small notch where they go around the corners of the truss. I've seen too many of the square bolts break at the sharp bend and I find the round ones work perfectly fine. I like the Rancho bolts because they seem to last a long time, I have 5-6 years on my fronts, no signs of stretching or stripping out. The larger diameter probably helps in that regard, they only get torqued to 30-40% of their rated load.
