Hey. Is it possible install LSD in rear diff in Mondeo Mk1 4x4? If yes - from what car? And what is a symbol rear diff (for example: 7.5'?). I'm not expert, and I'm from Poland so i don't have any ideas and mutch knoweledge about designation in my country. I thinked about LSD from Escort Cosworth, but I don't how that's a good lead. I have a turbo project with upgrade drivetrain, but shared 58/42 is not good for me. So i think abou LSD in rear diff, becouse change transferbox etc. from X-Type for better rear power it's not comfortable to change. Here is for example, my Video - and we can see small advantage front wheels.
