I'm thinking with a good clean cut and some sort of a guide so the 2 halves can be lined up exactly as they were before the cut, and with the 2" aluminum overlapping the top & bottom that there would be minimal leakage if any. But as a backup I could attach a gasket with RTV to the top section right where it meets the aluminum bar??
