I have a Schwinn Hornet I'm working on (you may have seen my build posts http://www.ratrodbikes.com/forum/viewtopic.php?f=21&t=21077). Here's my new problem, my tank is missing the horn, so it has a hole in it where the button would be. I really don't care if I have a horn, but would like to plug the hole with something. It can be clever (I thought about a red light) or ordinary (a rubber plug of some sort). Just wondered what some of you guys have done in this situation.
