water in the cowl area

[mestorod70]

Help please.
Can someone tell me how water is supposed to drain from the cowl area
I dont see drain holes...and its a perfect place for dirt and leaves to get stuck
at the lowest part and cause rust.
I found some rust under the upper cowl panel on my 70 and may have to cut
it off ...sand blast the area and weld back on.
Has anyone done this...and or drilled drain holes in the sides.
Thanks for any advice.
