Cowl drainage fix?

Hi All, Is there a fix for the poor cowl drainage that lets debris and moisture rot out the lower rear corners of the J truck front fenders?
Thanks, Chris

remove the vent cover by the foot area, remove debris and cut a screen (Post edit: aka bug screen, the plastic version is easier to deal with, adding pict sat) of the appropriate size to fit under the hood vent...

For my '91 I bought some black metal mesh and cut it to shape then stuck it underneath the vent at the base of the windshield, like Michel said above.

It works great, no debris ever gets through it and you'd never know it wasn't that way from the factory.

Yes, however I use the plastic mesh that is used for covering a house gutter. Unlike the original slots in the cowl grille, the debris that can pass through the mesh is small enough to pass through the drain hole in the cowl pockets and the fender bottom.

It is actually pretty easy to remove the front fenders and then take a 2" hole saw and cut a hole right above the "floor" of the vent. Easy to clean out. Then use screen. Never clog again.
