I have a battery with the twin top posts and the side screw terminals, is there any advantage to hooking up another ground from the side screw negative terminal and mount it to the body/frame too?
Thanks

really depends on the electrical load of the vehicle and/or the size of the primary ground lead.
I know of a few 1970 and up cars that have an additional added ground from the engine to the body that once added cleaned up radio noise.
your results may vary
In that era, there were a lot of low band VHF radios (Nebraska and Colorado State Patrols for two examples) in police and fire (San Francisco Fire) use. They were a lot more susceptible to ignition noise. The factory ground system would include bonding the engine to the firewall, the hood to the body, and trunk lid to the body. They would use braided copper for flexible bonds.
There was also an option to have an antenna hole punched in the roof with a Motorola mount antenna connector and coax run under the headliner down the post and into the trunk. All of Colorado State Patrol Fury I s were ordered that way. It saved the radio installer (at that time, I was one of them) time installing the trunk mount radios.
