By the way you can install these pretty much with homemade tools. You need some oil, and a good quality bolt to crimp the device, and a "through hole" with a handle for a bushing. That needs to be hardened, you can even use an oversize nut and hold it with a wrench. So the order would be bolt....some hard washers, your nut, more washers, and the insert. Holt the nut, twist the bolt.
Hmmmm found this, but you want good quality bolt/ nut and oil
