i think the next thing you should think about is brakes. you may want to do some suspension work later, but make sure you can stop first. on the site below i read that later model 620's came with front disc brakes and electronic ignition standard. do you have front discs?
i googled datsun 620 and this came up, you probably have allready seen it, but here is a link anyway, lots of info and some good links on site
