I purchased a perforated aluminum sheet from Lowes for $26 with enough material to make 4 covers.
It was pretty easy because it is a flat area and there is a 1/4" lip on both sides that you can tuck it under.
I secured it in 4 places with .020" safety wire.
I feel better now about riding thru bugs as it was a pain to pluck all the bugs out with a pick,to say nothing of rocks and pebbles.Also it was very easy to bend those cooling fins.
