Post a "wanted" ad in the classifieds. All 70-77 hoods, 2 door or 4 door, are basically the same and will bolt up to any car. Except of course the 71-72 year "grabber hood" with the scoops.
Expect to pay a premium price for an original 71-72 Grabber hood in really nice shape - if you can find one where the front hood lip is rotted out, you can weld a good front piece on from a flat hood to repair it
