You aren't getting spark? Well, if the coil tests good, it's time to move further down stream. Looking at your coil to distributor wire, it looks pretty old, I'm guessing you haven't put new plug wires on her in a while? Keep in mind I don't own a Z, yet, so this may be -way- off base. After looking at pictures, though, they look like standard cap/rotor vacuum advance distributors. Try this, pull the distributor cap and disconnect the coil, have a friend crank the motor. The rotor on the distributor should spin freely as the motor cranks over. Check the rotor to make sure the contact on the end of it is still attached, in fact, check all the contacts in there. They should be shiney and nothing should look broken. If in doubt, replace! Rotors and Caps aren't particularly hard to do and, for most cars, aren't super expensive. Take the wire that connects to the cap and ignition coil, grab a multitester (cheap at radioshack) and measure it's resistance. Should be minimal! If nothing registers, then the wire is broke, and needs replacing. The wires in the pictures look pretty old, so that might not be a bad idea anyway (the coil->cap wire should come in the full spark plug wire kit). Last, but not least, if the plugs are old, get new ones! Ok, I was wrong, this is the last. Make sure the spark plug wires are connected in the right order. Trust me, this is easy to do, especially if you think "that can never happen to me", because trust me, it can! :paranoid:
