Sorry the anchor light has already sold. As for the top... one did come with my 1978. I need to inspect it to see how much of it is there. I am sure it is not in good shape but might be useful as a pattern. I will dig up my copy of the 1974 Carver brochure to see how the 74 compares to a 78.
I have scans of the 1974 Carver brochure if you would like them. That year is missing from the archives on the Carver website.
I need prop shaft and parts where shaft passes trough hull for 79 Mariner 28. Do you have this and if so, what is the length and diameter of your shaft? You call call me at 770-753-0931
