Denny, Denny, Denny, dont be so surprized. If you ordered a entire kit for the fenders and cab, you will find a whole lot more of that roofing felt. We replaced ours with a product call ice and water guard. It like felt, but thicker and has a lite glue on the back, that helped to hold the part in place. It comes in a roll that about 3'x66' long, so it should last us several trucks. We found that several gaskets or seals were very lacking when we bought into this kit idea from Chevy duty. We shall use a differnt method on the next truck. We have started a list of the thing that dont fit, that were sold to us as "like the orginal". Its getting larger and a little costly, but that part of the learning curve of trucks.
