Cannot reinstall the door handle removed from a 1998 e320
I recently changed the door latches on both front doors on my '98 mb e320. The driver side was the first and went back together nicely. The passenger side, however, didn't work as well. After installing the new door latch and the other components, I tried to install the door handle and it wouldn't slide all the way forward unless I pull the handle out about one half inch. The handle then stands that distance away from the fully flush position.
Looking in from on top (the window is still out), I can see that the catch on door handle is hitting up against the external release tab on the door latch.
What am I forgetting?
