I've got a couple OLD pics from my install back in 2013 here: This particular pic shows the trimming on the center I had to do to clear the water pump...it just took a couple minutes with a dremel tool and a cutoff wheel. I also cut the 4 tabs off the edges (although not needed, it does clean up the look).
