If you have a 2001 gas CC I'd stick with the fluted, cast-sheaved driven clutch. The smooth, steel-sheaved steel driven clutches are designed to work with a drive clutch Club Car no longer offers or sells anywhere as far as I know and hasn't been used in Club Car gas carts since early 1987. It seems to me that a lot of cart manufacturers are selling the steel-sheave driven clutches for newer carts but they're not 100% compatible.
