1984 nissan datsun 720 pickup truck

1984 Nissan Datsun 720 Z pick up truck. I got it to pass smog a little over a year ago and then it stopped running a couple weeks after. Put new tires on it before it stopped running even the spare is new. Also the shocks, radiator, front rotors and shoes, plugs, plug wires distributor cap and rotor and a few other things have been replaced new. Also had a valve job done on it about a year prior to it not running. It does need some work cosmetically due to rust and and a new bench seat. And the truck is on non-op at the moment and has been sitting for about a year now. I have put quite a bit of money into the truck But it’s time for it to go.
