Brett,
Thanks for your response and it made me think about the information I had included in my previous post, so I went to my coach and took some measurements,
The 96" guard is 95" behind the wheels and approx 14" from the rear of the coach, more or less directly under the rear radiator. My thoughts for the replacement guard is to install on the tow hitch brackets. Would this change your comments regarding improving the air flow?
