I have all my lights working but no brake lights .This points to the turn signal switch. Is this posable with all other lights working?

Yes. Have you checked the actual brake light switch itself?

Could be signal switch, but more likely a bad brake switch.
The way GM signal switches work from that era is that in the middle position it connects both brake light filaments to the brake light wire. Putting it in the left position connects that filament with a switched power supply from the flasher. Unlikely that both contacts in the switch are bad. More likely that the fuse or brake light switch has failed.

3 hots come in from: brake switch, turn flasher and hazard flasher (if so equipped, not sure about 65 hazards)
then 4 wires out to each corner

Jump a temp ground to the light socket. If a light works then start checking the rear ground for the lights
