Thanks for the kind words. If I remember correctly, I took the placement for the mount point directly off the FEL bucket. In other words, I measured the distances on the bucket and just replicated them for the forks.
If that doesn't answer your question, I'll try again.

Thanks. I've seen forks that attach to the FEL bucket. I do not think the chain hooks were used in any way. Using FEL bucket forks would make putting them on quicker, but I am sure they could not lift as much weight. And, personally, I'd be concerned with bending the bucket where they attach from trying to lift too much weight. Good luck.
Is it a small piece of steel pipe welded to the side of the mount for the mounting PIN to go through and a hole drilled in the side of the pipe for the clevis pin to go through? Thanks again.......
That is exactly what it is. I was lucky enough to find pipe with an undersized hole so that enlarging it for the pin was fairly easy. By far the hardest thing for me to do was to drill the hole in the pipe for the clevis so that it was exactly centered so as to line up with the hole in the attachment pin.
