Should be ground strap/cables between batt/eng and eng/frame. Not sure what year started it it but the later ones also have a ground wire from the batt to the body(fenderwell I think).
Odds are in NJ the body mount bolts are pretty rough by now and that'd be the only body/chassis ground so I would add a ground strap between the batt and someplace on the firewall(free of paint etc). I've added that extra ground using marine batt terminals with the post allowing multiple cables to a couple rigs where the dash/lights/gauges etc were acting goofy.
