TODAY is a Great Day to visit our Store and order the parts you need for your truck ! ! !
You can always drill a hole in the cover too, especially if you need a breather.. Of course you need to remove the cover first, drill a 1 1/4 hole, and clean up the burr before reinstall. Auto parts stores and catalogues carry a grommet seal and breather for the hole you drill. if you want to that is.
