KA24DE-Powered 1978 Datsun 620 King Cab Pickup w/ 5 Speed

KA24DE Powered 1971 Datsun 510 Four Door Sedan 5-Speed tranny
-In October 2025 it became a runner after a restoration and modification process that started in 2017.
-Less than 300 miles (in chassis and refreshed engine) have been put on this 510 since the rebuild. 
-Runs, drives & brakes as it should. Mechanically sound. 
-Miles will keep going up as the car is tagged, registered & regularly driven around town mostly during weekends.
-It has a clean FL title in current owners name and is currently tagged & registered for street use.

Lots of new parts were installed during the restoration process. Please read the entire ad to find out.  Furthermore, this is still an ongoing project and needs finishing of some systems but is a solid foundation ready to be taken to the next level. 

Needs to complete or tinker with:
1. wiring up head/tail & signal lights (only brake lights are working at this tiime). All the wiring needed will be provided with the sale. Is already there tucked under the dash and in a box under the dash. The wiring is already pre-labeled and it originates from the new Autowire fusebox and relays that I installed inside the glove box. 
2. There is no horn or emergency brake
3. There is No carpet or no sound deadening material has been installed so makes the car noisy at cruising speeds.
4. Weather stripping for each door and the trunk has not been installed but will be provided with the sale. This also allows noise (wind whistling & some metal to metal rattling) into the cabin at cruising speeds
 5. Small leak at base of Motor oil filter:  I installed a "Mishimoto MMOP-TPS Oil Filter Sandwich Plate Adapter" between the motor oil filter and the block to allow for the installation and hook up of the oil pressure gauge.  I tried once to fix, checked the integrity of the "O-ring" (was good) and torque "almost" to spec ( tried apx 30 instead of the 35 ft/lbs recommended spec) the Mishimoto sandwich plate but it still has a small leak. I have not tried to torque again at the 35 fr/lbs torque recommended spec.
6. Small leak at Rear tranny seal;  I just installed a new one but I guess did not do it right.
7. Small leak at Differential front pinion seal: **A new seal (in its box from Z Car Depot) for the pinion gear where the driveshaft hooks up, will be provided with the sale.
8. windshield wipers not installed  but motor (with new bolts from Z car depot) and wiper arms will be provided with the sale. The car has never been driven in the rain but I have applied 'Rain-X" in the winshield just in case.
