I picked up a 52 GMC earlier this year. It's actually in pretty good shape. Now winter setting in here in Wyoming so it's time to start fixing things. Right now I'm working on the ooga horn that was on the truck. When I took it apart it looked like it may have gotten hot. All the chemical insulation had melted and oozed out of the electrical motor. The motor won't turn. The horn probably not original to the truck. But I think it's old. It had steel rivets holding it together. I'm in search of a electric motor. This one is sealed. I'm not having much luck attaching the pictures. Hope they come thru as it won't do much good if they don't.
