If I recall there was some kind of strap on the engine side of the instrument panel (56 E series) but it was rusty and not worth rescuing. Seems it would be hard to hear it mounted in the engine compartment. Guess I can put it where its handy but but where did the factory put it??
Still haven't found my manual dag nab it!!
in the engine compartment on both of my trucks. And you're right, you can't hear it with the engine running. My '59 is self canceling , but the '55 isn't.
