I am not sure if everyone is afraid to touch this one or no one has any feedback.

I did find some local help that suggested that it would be wise to keep the drain functional rather than fiberglassing the whole thing. And that I should just be able to take a piece of hose or tubing and stick it down the hole and then fiberglass around the tubing.

It seems to me that if the hose/tubing is not directed correctly, I might just be shoting all of the water back into the passenger compartment. Maybe it will be obvious when I get in there.

Any feedback?
