It’s me. I have bought these: 46.06US $ 6% OFF|4x4 Suspension Spring Rear Comfort Double Shackles Lift Kits for Hilux Vigo 2005 2014|shackle| - AliExpress - https://a.aliexpress.com/_mNYA6hNSo Matti, who makes those weird looking rear shackles?
and then I modified them. Now there is ball bearings and more J-shape.
