At this point I would be afraid to drive it a mile down the road let alone 60 miles to Vonore not knowing if the brakes will work properly or not. I did push the pistons out a few times and they seemed to loosen up but can't be sure what might happen when driving.
Plus, the accelerator pedal rod pops off after a few minutes of using it due to the fact that I had to bolt the pedal to the rusted floor with a single bolt/washers combo. One of the original bolts is rusted to the floor and the other is broken off. So the pedal twists a bit and the rod pops off.

Update:

Used some PBlaster on the front caliper and so far, seems to be working correctly

Bought a multimeter and began troubleshooting. Began with the fuses. Lo and behold, two of them had no continuity even though they looked good. Did have some corrosion on the ends, however. Swapped out with good fuses and the gauges, wipers, etc are working again

Engine starts and runs though a bit smoky. Idles good but will only rev very slowly
I can bring it up to around 3k. A few loud back fires resulted. When I let off the gas, the RPMs come down slowly.

Guess it's time I adjust the valves, check timing, etc
