I'm having a hard time finding out what the rubber grommet that attaches to the cowl, where the hood meets near where the steering is, is called. Does anyone know what this piece of rubber is called or where to find? I cannot even find it in the parts manual. If this isn't manufactured anymore is there anything I could use in place of this? I attached a picture with the area circled. The tractor is a 4020 1966. Any help is appreciated!
