Rusty, these horn arent something you can just poke and dig a screw driver around in. Several el circuts in them. Loks to be a couple of place to adjust them, but who knows what to adjust. Looks to be a set of points in them, along with a viberator, and some diodes. Cloth wiring eveywhere in there. Too bad that horn guy only does 64 and up. Got a set from a 50 truck, but there differnt than the 47 ones, and only the lo one works from that set. Thouhgt i could just change out the inside part, as i powered coated the shell and cover of mine, but the bolt patterns are differant. So typical of chevy parts. The same,but not really. Maybe i should find someone to teach me how to restore them, and start a businees.
