Dave, having the bottom-half is better then not having any ring at all, and if you already have the top-half, a "good" welder of "pot" metal can make a complete ring of the two halves.
There is/are rings for that year that someone makes-up in "SS" that doesnt break so easely.
Hope this is an answer to your question/comment.
Good Luck, Jim
