rod storage

My '78 23 cc seacraft's previous owner for some reason removed the wood rod storage pieces under the gunnels and threw them away, so I have no pattern to build new ones and they provide much needed support to the gunnel. Just wondering if anyone may have any old ones or a pattern for me to use to make duplicates. I am planning to make the new ones out of starboard and can make them with no pattern but would really reduce the cutting and trimming if I could come up with a pattern.

Thanks, Scott
