New OEM hood blankets are very very rare nowadays. On the 2003-2004 trucks the hood prop often damages the hood blanket and makes it unsightly. There are a few aftermarket thermal blankets that you can purchase to replace the OEM product, they are similar to sound deadening sheets used in doors and other places in everyday vehicles. There is also a vendor that has a cloth product to cover your old blanket to make it look new and fresh again. Here are some links to help you locate replacement material,
