Under My horn center cap on the steering wheel, there's a spring, nothing else.. Depending on which way I set this spring before installing the center cap,I can get the Horns to blow either continuously, or not at all !! Is there something missing ?? Could someone whose Horns work just fine on a '67 Plymouth, take a picture of what's under the center cap and send it to Me?? I've looked thru several manuals, but can't find any info or diagrams or pictures regards the Horn ring, center cap,spring, or anything !!!Mopar friends/mechanics no help either.. Can someone help, please ??
