Hi Coolvibes, We didn't really change too much over. The new axle mountes just like the old one. Make sure that the center support rod above the diff goes all the way into the trunk from the bottom. We bolted that in first to hold the axle steady. Then we proceeded to jack up each side until all the rear suspension stuff lined up. Shocks and stuff are the same I believe. I think I ordered rear shocks for a 72 W108 and bolted them in. You can probably order shocks for the W110 and be fine. Your choice there...

The only thing you have to actually change is the compensator spring above the differential itself. You have to unbolt the hydropneumatic compensator and put in the stock spring from your 67 W110 rear end (We still have to change ours so I don't have any tips on that yet).
