OK, enquiring minds (well, mine) want to know. Moss sells a few basic gas caps: 202-750, covering 1962-69 202-755, covering 1970-74 and 1976-1980 202-765, covering "1975 cars with single carb and no cat" The Moss rep was unable to tell me why 1975 B was so special as to get its very own cap. Surely there is a story here? --
