So I started thinking... If you have an old tanker, and it's customized, why not do something unusual or rat rodd-ish with the electric horn? Has anybody changed standard horn units out for other unusual horns of some sort? I've seen people put old doorbells inside old metal bicycle tanks, but I don't think i'm going to do that. I've got a tank coming for my Hawthorne soon and want to do something interesting with the horn- has anybody seen an idea that stands out, or done something sifferent themsleves? I'm thinking that something like a 1930's Model A Ford- an "ooga" horn- would be really cool inside a tank, but don't know that a reasonably sized unit exists or could be put inside a tank. Any thoughts?
