Hi Folks... Has anyone out there dimpled the battery box for a drain? How would one create that counter sink? Does it need one? I built a new box with a flat bottom. I just ordered a tray for the battery itself. What I was thinking was to use a piece of copper flared to fit the dimple secured somehow...haven't got that far yet.. so it would be flush or slightly under. I don't know if the original box had a drain or not..it was so rusted out. Anyhow, suggestions? Thanks, George
