sunroof drain tube help!!

I am just reassembling my transplanted sunroof assembly into my 74 duster. I can't figure out where the front drain lines exit the A pillar. I have checked the service manual for the sunroof, which was of no help. Anyone out there have a sunroof abody that knows were the drain tubes actually drain to? The roof has been transplanted from another car, so it is likely missing a hole somewhere.
They come off the front pan of the sunroof and go into the A pillar. I get the hose down there an it comes out on the inside top where the kick panel is. How/ where does it exit the body? Any help would be appreciated. Thx
