I searched similar threads but dont find the answers I'm looking for. I see the 2 drain holes in the corners of my windshield opening but I dont find the two 1 1/2" tubes that connect to them. I assume they rusted off. I cant find any drain hole leaving the cowl either - may have been obliterated in the sheet metal repairs. My question is could I just seal off those holes off without any major problems? It seems to me that, even with the drain tubes, leakage could occur where the crank out mechanism comes from the body. Good news is the vent drain seems intact. Thanks
