A CC may work with proper gearing (which is a tougher question), but for a buggy I'd say TC is better.
The 40 series requires a Jackshaft.
The DriveR unit goes on the CRANKshaft.
The DriveN unit goes on the JACKshaft.
A chain connects the sprocket on the Jackshaft to the sprocket on the Axle.
How big are your tires?

The CC you would want is probably close to the price of a knock off 40 series. You would have to install the jackshaft with the 40 series tho.
Maybe something like this...

It comes with a #40 Ten tooth Sprocket. Match that with a #40 60T on the axle.
It also comes with a 14T Sprocket, which you might be able to use for more speed (depending on the size of your tires).
I have a question. When gearing a 390 kart.....
Since it has about double the Torque as a 6.5HP, can you cut the gear ratio in half?
With a CC, I imagine you would have to engage at a much lower RPM to avoid engaging at 30 MPH.
With a TC, you can probably get away with a closer to half, cause the 2.5x advantage from the TC at engagement??????????????
