Most 7 and 8 speed freewheels and cassettes were 5 MM center to center on the cog. Cog thickness and space between were sometimes different, but as long as they were 5 mm center to center on cog...was fine. So Sachs, Most Shimano, 7 and 8 Campy, Sunrace, and perhaps a few others will all work with the same shifter and rear derailleur....if it has enough travel. Whether the rear is spread for 8 (130 MM) and has room, is another matter. I know I shifted successfully a bunch of Sachs 7 speed freewheels (had a cog board with about all the cogs) with 8 speed campy Ergo shifters (one shift blocked off), with a rear that was spread less than 130 MM, but had room for 7. Love that frame.
