You may need a 0.5 to 1mm washer on the axle's drive side to space the small cog away from the dropout. Older frames often have pieces/parts in that space. Newer cassette hubs count on that space being clear of impediments.
If you're running a ten-speed cassette, you need a ten-speed chain.
If you're running a nine-speed cassette, you need a nine-speed chain.
If you're running an eight-speed cassette, you need an eight-speed chain.
