Ahhhh... I knew this was going to happen....
I bought these at a motorcycle shop in Conyers the same day I bought the Honda from the private seller. I don't remember the name of the shop, except that it wasn't a dealer of motorcycles, but more like a "we sell jackets, helmets, and everything but bikes and parts" shop. And since it was three years ago, I don't have the box anymore either. I do know that the company was in San Juan Capistrano, California. Or maybe it was the distributor. I remember it because of the swallows returning, and I visited the mission there when I was in grad school. I wish I could remember more, but again, at my age, the memory has turned out to be the second thing to go.
