Hello everyone. New guy here. I am replacing the transom in my 1987 Hewescraft River Runner. The plywood has an aluminum skin on the outside and inside. There are two open drain holes above the splash pan that have a hollow aluminum tube. The tube is flared on both ends so I had to straighten the flare on one end in order to get the skin off. I pretty much destroyed them in the process. Does anyone know where I can get replacements? I tried Hewescraft but they didn't seem to know what I was talking about. Any ideas would be appreciated.
