Have an air compressor? If so, BUY the cheap Harbor Freight air cutter that uses the little (I think they are 5") cut-off wheels. You'll laugh along with the sparks cutting that sway bar into manageable chunks of recyclable steel. I think I spent less than $20 for the tool and a couple of discs and sliced right through a 'hardened' steel lock hasp for which the key had long since been lost. It didn't even take a fraction of an inch of the disc to do it and only took a minute. And what a spark show!
