Gearbox destroyed !

The reason the work is so delayed on the Range Rover is because the original gearbox was destroyed when the propshaft broke off from the U-joint. The result was what you can see on the photos below

To make matters worse, I bought a reconditioned gearbox, which proved to be faulty ( gear crunch when shifting from 1st to 2nd) , I complained to the supplier and they send another one, which is better in terms of shifting but still far from the original gearbox.
