I have two of the "clip on" hooks along the top edge from BXpanded.
I also attached a hook on the bottom, back edge of the bucket. Having it closer to the tractor increases its lifting capacity. I drilled a hole through the thick bracket that the bucket's hydraulic cylinder attaches to, and then used 3 or 4 links of logging chain, and a 1/2 inch grade 8 bolt to mount the hook. (Shamelessly copied another TBN'er.)
I don't think that you have that large bracket, as I believe you've got two bucket cylinders. If you can figure out a way to mount a single hook somewhere, do it, even if it's not as far back as mine. It makes lifting things much easier, and more centrally balanced. Having two further apart is good when you need to balance something, but it takes more messing around trying to get the lift squared up.
