without a welder you have two other options off the top of my head, the first being much preferable to the second.
1) get a plumber's torch that runs on propane. Get bolt extractor sockets for that general size of bolt. Get the bolts hot, but not so hot you catch the bushing on fire. Use the extractor socket to the turn the bolt while it's smoking hot just a quarter turn or so. Hit the bolt with Liquid Wrench, let it cool a bit, then twist it the rest of the way out.
2) With a dremel or cutoff tool or grinder, grind some new, smaller flats on the bolts. Pray to the mechanical Gods that they shine upon you. Use your impact bolt-head-rounding device to snap the heads off the rusted bolts because the mechanical Gods despise you. Drink a 6-pack while you ponder every bad decision you've ever made in life. Drill broken bolt with right-hand drill bit, pressing hard to ensure you break the drill bit off in the broken bolt. Drink a 6-pack while pondering if you've ever made a good decision in your life. Using the tiniest left-hand drill bit in your set that you haven't managed to lose or break, yet, attempt to drill into the broken right-hand drill bit while whispering a Detroit shaman chant. After breaking the small drill bit off in the larger drill bit stuck in the broken bolt, drink a 6-pack and ponder the meaning of life and whether it's worth existing at all. Using a cold chisel of improper length to get a good swing at it, attempt to convince the drill bit it wants to leave its new-found home. Good job! Now that you've chipped your cold chisel, gouged the frame, sway bar bracket, and sway bar itself, you can get serious about solving this issue with a sawzall. Drink a 6-pack because you look like you need it. Using the sawzall, remove the sway bar from around the bracket. Consider whether you needed a sway bar in the first place. It's late, so you probably didn't really need it. Replace the bolts you removed so the bracket doesn't rattle. Congratulations, you're done! Drink a 6-pack in celebration!
