Most of the stock unmolested mid 1960 to the early 1970 A,B and E body Mopars had there stock block ground straps back there Maybe not the same size or location but you can never have to many ground straps on our old muscle cars, can we Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)

I ground from the passenger side head to the firewall, ground from the voltage regulator to the firewall ground, ground from the negative battery post to the core support, and a separate ground from the ignition ECU to the body.
