No pics, and the Assembly Guide has only generic pics. I replaced my turn signal assembly a few weeks back, so let me see if I can remember anything valid. Is the "prong" that points down from the rocking part of the switch engaging the copper springs in the base that initialize the signal? You should see two thin, fragile, springy coper wires in the base of the switch. On a '63 they are in the upper half of the base, above the midline of the steering column. The prong pushes the respective wire closed to initiate the signal for that side (R vs L). If the prong is broken, it may be jamming the signal. If you can't get the signal to cancel by rocking the switch to the other signal, this could be the trouble. As for the horn, you said that it honks when you ground the wire. That would indicate a problem in getting the rocking action of the horn ring to close the ground circuit from the steering shaft to the copper annulus. I had to apologize to my neighbors in advance of working the installation repeatedly to get the horn to sound! The Contact Bushing that nests into a hole at 2 o'clock on the wheel transfers the ground from the action of the horn ring down to the copper annulus that you see immediately under the removed steering wheel, completing the ground from the steering shaft. Do you have this Bushing, and are the copper ends clean? http://www.impalas.com/1949-1966-chevy-horn- contac... All these parts, as appropriate for your year also need to be in place to allow the horn ring to float above the wheel, and rock enough to initiate the grounding of the circuit. http://www.impalas.com/1958-1960-and-1964-im pala-h...
