You are looking at the clean air intake duct from a 77 Ford F100 pickup truck, pt# D7TE-9D624-DA. Correct for 1977 to 79 Ford F100 F150 F250 F350 and 78-79 Bronco with all engines. Looks like there were 2 riveted mounting tabs on the front that rotted off. Tab in rear in place. No cracks. Will look nice under your hood.
