Honda's planned obsolescence has split them into the 1975/1976 and then the 1977/1978 camps. The mounting pins are in different locations. And it seemed when I was looking for the later ones for my '78, at that time they were commanding more coins than the prior versions. But that was a few years ago, so may be no longer valid. Much like the left hand electrics side case for the K1-K6s to get one in great shape commands a premium. Of course with my luck I am always looking when the market is hottest for whatever it is I need.
