Truck Builder, October 2003 has an article on reinforcing trailing arms- Strong Arm Tactics Installing Trailing Arm Reinforcement Kits

It's available on-line on ECE's website. The reason for pointing this out is simple...this article discisses how to reinforce a set of arms but you could also repair yours in this fashion if you're uncomfortable with just replacing the rivets with bolts. TX Firefighter is right, if the arms aren't bent just run a bead re-attaching the two halves...for a fix on a budget that will work nicely, just be sure to clamp the two halves together with the U bolts in their holes so you're sure everything will line up correctly while you tack weld them together. If you aren't comfortable with your welding skills get a quote from a welding shop and compare it to a price for replacements...if you're humble a welder may help you or just check on the shipping costs for Ripdog's arms.
