John, Ed (aka RivNut) suggested I post the parts I'm looking for in this thread. I own a 1979 Buick Riviera and am also located located in Wisconsin (Cedarburg, near Milwaukee). You wouldn't be able to find a headlamp warning buzzer by chance would you? It's located on the interior of the car just above the fuse panel (in the convenience area). The one I have now only notifies me that the key is in the ignition, but does not beep if I leave my lights on or don't buckle my seatbelt. If you could find one of those I would gladly pay you for it. Let me know if you go out to the salvage yard to look. If not, I completely understand! It's getting harder and harder to find parts for my 1979 Buick Riviera. Thank you!!
