For the life of me I can't seem to get my hands on ONE (1) black plastic pantograph insulator for GG1 30-2592-1E.
Someone on the forum offered me several for nearly 20 bucks.
My Lionel rubber ones will NOT fit into the hole nor adhere to the metal cab.
These insulators don't look like a typical rubber insulator. They have a very long bottom portion that fits into the shell.
