Convertible drain holes

[snowman]

I have found the dreaded tin worm behind both front wings on my convertible which is not a major problem as I can weld a new piece in and repair it .
My issue is with the drain holes , I know there are two at the botton of the sil behind the wing ,but are there any above these ?.

The drain holes are easy to spot running along the underneath of the sills, the holes are inside the horseshoe underneath the roof mechanism.

I poked mine with some thick gauge wire and then ran hot water through them, been fine ever since.
