Those fender induction cutout is original on this very late 74 car in the model year. , as production pieces shifted to newer 1975 featuresHey Mark, What's the big long (oval) cutout for on your fender there? Just behind the rad support bracket. Was that a cutout for a cold air intake bellows? My 76 has the identical indent in the metal there, but no cutout. Some First gens had a cutout into the firewall above the heater box for the cowl induction of course.
BTW ….that’ s a pic my 74 car s HEI Z28 engine plastered all over the internet from like 18 years ago. Not quite that nice now …lol
