nexusheli,
I used gutter guard that is normally used to keep leaves out of gutters. For the top front I melted down the plastic rivets and pulled the chrome from around the grill.. applied the gutter guard bending the edges over the edge of the grill insert.. then I put the chrome grill back on and melted down the rivets. For the bottom there are clips that need to be removed from the backside.. then the guard can be installed and the clips but back on, bending over the edges just like on the top grill... For the back the same was done as on the front. It only took about 45 minutes...
