I think you're going to have problems using Mike's baja kit with that belt drive system. It may be as simple as drilling a couple holes into the rcm side plates, but I doubt it. Probably going to have to mill down something here, add spacers there, hope it lines up... You know the drill. Parts of the 4wd belt system appear to attach to the side plate, and other parts to the engine and clutch. Exploded views would help you see what you're getting into.
The Kalee looks like it has a wider chassis, so I'm doubting mikes kit will fit. Lots of pics of it can be found here tho
