Where is the circut breaker under dash located, is there one under the hood. Vehicle won't turn over, no interior light or horn. Battery and cables new. Thanks,
The only circuit breaker on a '67 is for the headlight rollover switch, and it's mounted on the driver's side hinge pillar just above the courtesy light, above the kickpad.

Sounds like you have the "big red wire" syndrome, which is a common problem on a midyear. Battery power comes into the cabin through a 12-ga. red wire in the inboard 8-way multiple connector on the engine side of the fuse block; carefully remove that connector and check the condition of the mating terminals for that red wire in the connector and in the fuse block. Corrosion or overheated terminals there can create an open circuit, which kills power to everything in the car. Sometimes just wiggling the connector and pushing on it at the same time will restore the power, but that's a temporary fix that needs to be repaired.
Photo below shows what that connector looks like when the red wire terminals have overheated (due to heat caused by high resistance in a poor connection) and partially melted the cavity in the connector.
Thanks JohnZ I hope this is the problem

Excellent! Will call him in AM, thank you.

They might have the connector and pins ( don't forget a good crimper! ).
Never mind Lectric doesn't sell individual connectors or pins
( further info )
PLUS there is a good bypass in this thread ( if you want to be non stock )
Mine wasn't burnt, it was just old and needed some cleanup and a wee bit O pin re bending...
Don't forget the Di Electric grease on re assembly~

I know the value of a good pair of crimping pliers. I have one with inter-changeable jaws for most of the ones out there. Also some stand alone pliers for various European connectors. I was a mechanic for many years, good tools are essential.

Thanks for the information Mike.
