I think you're talking about the header panel. It might be different for a 70 Cuda, but on my 72 there were two bolts on each side that screwed in to the fenders. Then there were 2 bolts that screwed down in to the radiator core support yoke (on each side of the hood latch), then finally 2 more bolts down on the core support yoke from the bracket off the header panel.
In this picture you can see the 2 top bolts and one of the two lower bolts. Again this is on my 72, a 70 or 71 might be different.
