I don’t see the desire for shackles. On the rare occasion I need a chain I almost always need it shorter than it is. I weld hooks on every bucket I’ve had. I did weld a D ring in the middle of the bucket to hook a rope if I ever needed to.
Nice Weld!! I have experienced the loss of too many shackle bolts due to hours of vibration: Suggest a good tight bolt with Locktite and extra vigilante inspection over the coming years.....
