You can always drain it in the future by removing the lower hose. How did you strip it? On my w123, the drain plug is plastic. Is yours metal? I think you can get universal plugs like the kind for oil pans when the threads are stripped. It's like a rubber stopper that expands when you tighten the screw in it.
