Is the *horn* (noise maker) itself broken? How are your wires?

Reckon you could just hit the 2 wires to a 12V battery and see if it lights off.

I believe so. Mine was never hooked up properly, so I am only assuming.

No, just a stock NP435 and a very light foot.

Wish I had an OD, but there's almost nothing out there for an FE block, and a Gear Vendors OD is $3000. If you have a 351/400, I think a ZF5 will bolt right on up. The gear spacing will be better, plus the OD and will really wake your truck up. That is, if you want to go manual. I think an OD auto could work too though.

ZF5 adapter kit

get this, notch the ZF5 tail end of trans for 205 to bolt up, measure correct driveshaft length, may need to get old ones rebuilt to fit, may not. May have some trickery to bolt onto cross member. Its a swap I may pursue

As for the horn, mine doesn't work. Being a MASHOLE native I just use the lucky finger or highbeams or left/middle pedal to get the point across.
