I believe the right side covers are the same for the 75 76 77 78 750F the left side covers are different between the 75,76 and the 77, 78 750F I didn't think they would fit but I just went out to the garage and checked and YES a 77,78 K cover will fit on a 77 F It might be a solution to everyone looking for the left cover for a 77,78 F. I saw one that needed painted and had no badges go for over $100. on ebay. You can get repoductions at Davidsilverspares for the left 77,78 cover
