Internal cover for tail light housing missing
In preparation for replacing the floor in my '70 Safari, I removed the lower internal skins. In doing so, I discovered that the exterior lower rear curbside skin had been replaced at some point in my Airstream's past. When the panel was replaced a hole was cut for the tail light housing and the housing was held in place using sheet metal screws at each corner. On the roadside, I see Airstream used an internal cover over the backside of the tail light housing. This cover is sealed to the skin and I see no leaks from it. Unfortunately when the curbside panel was replaced this internal cover was removed leaving the back of the tail light housing exposed. This housing is not watertight and allows water to flow into the trailer. Why it's not watertight is one of those Airstream mysteries. Does anyone have an idea on how I might seal this area against leaks? By the way, the replacement panel leaks as well but I should be able to fix that now that I have the wall opened up.
