plus the contour of the lower fender on a 70-81 bird are different then a maro. there is a slight indentation along the bottom portion of the car all the way down the side of the car it is very suttle but there.
also on the bird the center of the fender and door have a soft bodyline and the maro has a harder line.
A Pontiac should have a Pontiac engine -- otherwise it's just a Chevy in drag.
