Brought back from the dead.
3 year update:
Despite all the frustrations it causes me, I still have the Z!
It sat at my dad's house in Wyoming for two years while we figured out electrical problems. I live 8 hours away so I could only work on the car 4-ish times a year during that time. After some frustrations, we were able to get the headlights and turn signals working (cleaning the fusebox really helped).
With that all taken care of, in May 2014, we drove it from NE Wyoming to Salt Lake in one go (he followed in a separate car with tow ropes).
Except for a patch of snow on the road (that I hit at ~50 mph but managed to keep control) the drive went without hiccups.
In the last year I have fitted it with a new antenna and speaker, and tuned up the carbs a bit but not a whole lot else.
Back last November, the clutch started leaking so I replaced the slave cylinder and hose. I still had leaks and ended up getting yet another slave, a new hose, and a master cylinder. Leak free now.
I also had a brake leak at the stopper screw in the master cylinder, so I replaced the washer (caused me problems for a few months).
And a few days ago this happened:
Radiator spilled it guts everywhere.
I replaced the hoses, thermostat, and cap. While I was doing that, I removed the inline coolant heater.
I have a rear transmission seal slowly leaking as well as a small oil pan leak. Those will probably be next on my to-do list.
