Few questions on Axle and Gearbox

[Marcus1991]

Ive got a 206 HDi gearbox sat in my shed, and i'm toying with the idea of putting it on my Dturbo due to a lot of motorway driving, the clutch fork looks different to the 306 HDi box, the gearbox i have looks like this http://www.google.co.uk/search?q=206+hdi...B640%3B480

But the 306 Hdi box/fork looks like this http://www.google.co.uk/search?client=sa...B480%3B360

Would the 206 HDi box fit somehow?

Also, got a lot of creaking and camber on the rear axle, needs new bearings, would you recommend a whole rear axle change or just to replace the bearings like these?
