Starting body work on the 49 burb. Got some lower rear corners from metalman and they are absolutely gorgeous. After removing window frames discovered what looks like drain holes in the window sills. The holes lead to a channel under each sill that has a short hose attached to it. Can't see the other end of the hose. If these are actually drains where does the hose lead to and where does the water drain to? Anybody out there run across this? Thanks. Weeds
