What the heck am I doing wrong with this '74 Valiant hood?

A couple of thoughts ..

There are 2 hinges for 67 up. one had adjustments in the hood the other has adjustments in the hinge. If you have the wrong hood mated to the wrong hinge things will not line up properly.

67 to 72 notice the front most "hole" and rear vertical slot

Also

The adjustment is counter intuitive, to lower the rear of the hood you raise it in relation to the hinge.
