Need help finding a peice

[NWO Fisher]

Hello, I am restoring my transom. Wood is epoxy resined, boat is aluminum. There are 2 ports that allow water to freely leave the boat near the motor that I am unable to find.
1" diamater, and the transom with wood is about 1.8" long.
can anyone direct me to an item I can find online? I would like it to be aluminum. I have only found brass and dont want corrosion

If I understand correctly they are drain tubes, and use a flaring tool to install
