another slightly different way if the rubber is shot-
My lower bracket on the bumper itself was broken, just like all of them it seems, and the rubber pad was also ripped and useless
I ground that out, and I bent two pieces of 3/16ths steel in U-shapes that matched the contour of the inside of the bumper
I then wheeled off the rest of the rubber pad and welded the U's to the bumper shock. Im sure you could bolt it same way though
looked like this ultimately-
Similar to the OP, only a pair of carriage bolt tops are visible, though top and bottom vs both on the bottom. Also I used stainless steel bolts
