[MutchlersKANDIkg250a]

Ok, so I'm new to the whole buggy world. Been interested for a while. A friend recently gave me my first one. It is a Kandi KG-250A. The reason he gave it to me was because the transmission grenades. He said something about a torque converter. I have looked around a bit, but I don't know what one will fit. It has the water cooled 250cc engine, and the separate gears for each wheel. Any body know? It does have a forward and reverse geat box. The shaft from the rear of the engine case going to the gearbox is splines. That's the one I'm trying find out about.
