My datsun has 98K miles, I rebuilt the top end last month. My friend jhon 510 helped me out. So Far I just cut the front springs a little. I insatlled a aluminum Rad, Installed a clean sound system, I painted the wheels black and used corolla beauty lips on the wheels. I am looking for datsun hub caps, right now I'm using the corollas as well (I would Rather Not). I'm having overheating problems right now, but hopefully rebuilding the top end. Rebuilding the carb,changing the rad, Thermostat, pump, hoses, tem sensor, alternator,filters, and all the little things I have done will take care of the problem. I think I was running lean on top of my Head gasket being bad, and the Radiator half clogged.
