Cobra Hawk,
You can't have too many grounds. I added extra grounds under the dash as well as a braided ground from the engine to the frame. Electric fuel pump should be close to the tank with a good fuel filter between the tank and pump. Be sure to mount the filter where you can easily remove the filter from the bottom, after the body is on.
Ditto on other comments on radiator and steering column.
