Manual gear box tourqe rating

Hi, I'm looking for some information regarding a manual gear box. 

I'm after a style like the audi quattro 2012 6 speed manual PJH / PNF. 

This is going to be for a strange project however I'll get j to this later. But ideally the front shaft needs to be as close to the Bell housing as possible, center line wise. Just like the box mentioned 

Is there any gear boxes out there that could take a fair amount of torque, above 600 ideally. It will be 2wd rear wheel application so the rear shaft will not be required, obviously I may have to look at a dog engagement if nothing is available. 

Kind Regards shane.
