Does anyone know if All standard alloy wheels fitted to jimnys can take freewheeling hubs as I'm buying a jimny and the centre hole doesn't look bug enough.

Hello
Its my 1st post. Just wondered if the gearbox on the sj413 is exactly the same as the jimny 2001. Also is the front/rear diffs interchangeable between the sj & jimny. Just trying to establish what sj parts i can use if the need arises. Many thanks
