64 Dart ground set up

I have ground straps from each head to the frame rails, & the ignition and distributor share an additional ground.
Curious here, isn't the radiator support welded to the inner fenders and frame rails? (I have a 68, the early A's might be different). Wouldn't that be ground enough?


later edit; I see from reading on, that the ground to the radiator support is apparently where the battery was giving the car its body ground. I didn't know that as when I got my car, it went from the battery to the block, then the body was grounded via a wire from the head to firewall only. As I've gone through my car, I changed it to how I described above, and the battery is in the trunk connected to the frame.
