I finally got around to getting pictures of the custom chain hitches that TBN's own AntrimMan fabricated for me. They were designed for a 3/8" chain, but I haven't purchased that yet. I have used them with 1/4" chain, and they work great.
Here's AntrimMan's picture from when he made them (posted in another thread a while back).
And here's my photos of them welded on top of some 1/4" plate to strengthen the top of the bucket.
