To anyone that has a problem with the felt being worn out in the window grooves.I have a 2005 T300 and my windows rattled terribly. The felt was worn out in the window grooves and made a constant noise when I was moving. I had no luck at my local bobcat dealer with finding anything that would work besides replacing the windows. I found a place to get the felt to go in the grooves of the windows. The website is Sutherland Felt Co. They sell a felt tape strip that is sold by the roll, and it has an adhesive to hold it in the groove. You can get it in many widths. It is in Detroit, MI. Google their site and call them and tell them your problem and what you need and they will get you fixed up. I took the windows to my local autobody repair and they installed the new felt. Works great now, no rattles. Also installed new window rubber for the back windows between the window and the cage. Got that from allskidsteers.com. It also has an adhesive backing. They sell it by the foot.
