My ground wire came out of the wiring harness and bolted to the lower front (towards the headlights) side of the radiator core support.
Where it comes from in the harness I don't know, I just know where I unbolted and bolted back up.
I don't think it matters where you bolt it to , I think what its doing is grounding the radiator support to the car because the bolts holding it to the car is only going thru fiberglass, so in a nutshell you need a ground wire from the radiator support to the frame of the car.

Hi,
I don't know if we are talking about the same ground and if the position has changed (mine's a 74). But the picture below I took looking in between the open hood and the radiator support, so the top of the pic is towards the front of the car. In a 74 there's a hole in the shroud for the ground.

Yours would have been pretty much in the same spot. You'll find the bolt hole in the radiator support. Clean the harness connector and the support for good contact.
