I went through this a few years ago, and just bought the swaybar brackets from the dealer. I don't have a parts truck, so I was going to have to chisel them off with a BFH and a chisel at the junkyard. That sounded like a little too much fun for me.
They weren't real expensive. I just bolted them in. It made a huge difference in the handling. Now I want to get a bigger one off a 3/4 or 1 ton.
