Can anyone point me in how to align a sagging rear door on a W124 - my car has one replacement door RL (rear driver side) which is slightly cocked downwards from the rear.

The hinges are welded to the B pillar on a W124 and the manual shows that I need a special tool to bend them.

Has anyone tackled this before. I need to move it about 1/8
