Yes I am getting no power. I did jump from the front park lights at the bulkhead and the head lights did come on. But everything on the other side of the bulkhead to the headlights is dead...

take the black bakelite electrical connector off of the HL sw & jump fire to the terminals on the connector which'll tell you if the prob is downstream or in the HL sw itself

The upstream input side of the fuse box. Jumper wires w alligator clips are real handy for this

For the headlights power will go out from the HL bakelite connector down to the dimmer sw on the floor then up to the firewall bulkhead connector then on out forward to the headlights. the taillights (small filaments in the rear bulbs)are a seperate circuit & go out from the HL sw to a pull apart connector inside the dr side kick panel then rearward w 1 more pull apart connector rearward (most likely in the trunk) from that kickpanel connector to the tailights themselves. On the taillights I'd take off the dr kickpanel & jump fire to the 1 wire that feeds both taillights and if no light continue to work rearward until you find the open. On the headlights I'd pull the front half of the firewall black bulkhead connector and jump fire from the battery positive to the 1 out wire to the headlight brights and to the 1 out wire to the headlight low beams. This'll tell you if the prob (the open) is forward closer to the lights themselves or upstream back from the other (rear) half of the firewall black bulkhead down to the floor dimmer sw (I'm assuming the dimmer sw is getting fire) & if not from the DS to the HL sw. unless there's been excessive amperage flowing/frayed insulation (rare on the insulation prob) wiring goes bad (open or high resistance) at the terminals/connections at the ends

dimmer sw has 3 terminal. hot in then it's switched to either the high beam wire out or the low beam wire out. the Hot in is dead? This hot in wire is fed by & goes directly up the black bakelite pull apart connector on the HL switch.

We're dead from the HL sw down to the dimmer sw. If you jump to each of the "out" wires at the dimmer sw & you have (bright/dim) headlights and if you jump fire to the 1 wire in the connector at the HL sw and you have lights then the HL sw (or possibly the female terminal in the connector) is bad
