Its about $300 to get gaurds rolled from a panel beater. You can get it done for free if you have a mate with the tool

Probably best to get it done properly though.
TRD is a 30mm drop and IIRC king low is around 35mm.
On the note of sway bars, is it possible to bend your own piece of steel into a sway bar. I was going to weld two together but since thats heating the original suspension component thats a cert issue. Next idea for me is just get a 17mm steel bar and bend it into the shape I need

Would this work?
