I did away with the teak handrails on deck completely last year. I had a stainless set made that I ordered ordered thru Bosun Supplies. I think they were about $95 each. They look fantastic on deck - a more modern, racy look. They thrubolt to the old teak rails below that were still in good condition. The new stainless rails came with a larger diameter bolt than the wimpy 3/16" bolts that were original. I highly recommed this upgrade.
However, I still have all the old bolts. They're yours if you want them. Just let me know.
