Could they not us the same 1 1/4” opening?

If the lower hole was for the drain tube, I presume there is a grommet or something that is suppose to be fitted there … otherwise, it is allowing more stuff in than out.

This hole looks like there may have been a cover or flange fitted to it at one point as there are 3 - 4 rivet holes which look like they held something in-place over (or in) the hole.   The other side of this hole is in the fender well.
