Which clutch do I need? 2002 Sportsman 500

Just picked up a 2002 Sportsman 500 for cheap due to the fact that the previous owner says it needs a new clutch. Found some new clutches online before I bought it and decided it was worth buying and fixing. Got it home and the clutch is indeed cracked, likely due to corrosion. Only problem I’ve got now is buying the correct clutch.

Went to the Polaris site and found part number 1321976 (replaced part 1321632) and part number 1321706, the latter of which is listed as a "wide" clutch.

How do I tell which clutch I need?
