<VV> LM body water flow venting

[taruffi57 at aol.com]

On my '69 coupe, I have flushed water through where I have obviously  
removed the plastic front side vent panels.  While running water (front end  
elevated and rear rubber plugs pulled), I noticed that water was coming out a  
small hole right in the 90 degree joint of the body front door sill.  In  
other words, when you open the door and look down below the lower hinge  -  
actually this is right at the top of the rocker panel area and water would  run 
out to the outside of the car.  Is this small opening supposed to be  there 
to help vent out water?  There is no rust evident on the outside of  the 
sheet metal in that area but I suppose it could have rusted through from the  
inside.  Water comes out both sides and the holes appear to be same size -  
although they are quite small.  I need to know if I should tell my  
bodywork/paint guy to weld up these holes.
 
Thanks for any info.
