There are an overwhelming number of problems with it. Bush has a weathered appearance. It seems too quick to bolt through the undergrowth. Following the passage of the nut that secures it, there should be three threads visible. The hole in the bracket that formerly accommodated the identical bolt is now too large. There is an excessive distance between the return on the bracket and the position of the bolt used to hold down the bracket. And is only one bolt. Is it the appropriate length? Did it not also display any loose threads once it was done being stitched?
After confirming the location of the shims that adjust the fore and aft position of the wishbone end, I would weld it into place. You will need a longer wishbone bolt with a minimum strength of 8.8 as well as a new bush. Ream all of the holes to ensure that the bolt will fit snugly, then choose the appropriate bolt.
If you are merely going to be fastening the bracket to the wall, place two bolts near to the return or bend and one bolt in the middle of the rear edge.
