I got some flat head carriage bolts, but the head was smaller than the plow bolt. I finally decided to modify an elevator bolt. With the bolt in the bench drill, I used a file to take the diameter down, and then a grinding stone in a dremel to profile the countersink. I could go a little tighter on the countersink edge, but I am satisfied how it turned out.
