I dug them out and compared them side by side. The only differance is in the hinge part. The '72 set has a gear arrangement, while the '74 doesn't have that. The piece that bolts to the hood is the same, as is the part that bolts to the inner finder. Both sets are in very good condition, and both sets came off cars that sat for years, so they haven't been used that much. The '72 set is painted yellow, and the '74 set is in gray primer.
