installing screen under Duster's air vent

My freaking 96 ranger shoots out the vents pounds of leaf and dust debris for some dang reason. And all I do is leave it in the woods for weeks on end. It is amazing that the factory didnt have a better design than that even in in 96.

Here is what I did for a couple reasons. I drilled a 2-3/8 inch hole level with the inner floor of the cowl on both sides. It gave me access to the cowl area from both sides so I could sand blast up in there then use eastwoods inside frame coating in there (took me longer to get all the sand out than the rest of process combined). But also the holes are the lowest points in the cowl system and the hole is large diameter which will allow all the debris to blow, fall and drip out on both sides and may end up lodged between the door pillar and the fender. .
I just augmented the existing cowl drain system basically which is there anyway. .
