I have done the Tarus motor conversion, in fact, doing it about 10 years ago, I could of been the first or at least the first to publicise it. I had talked about it on the Email Forum.
I experienced a similar problem with the window motor gear not going deep enough to fully catch/engauge the teeth on the door mechanism. What I did was to machine a small portion of the motor mounting surface to make the motor sit deeper. At the time there were many motors to choose from, but I chose the Tarus because they were FREE. I never got around to writing an article because my pictures came out blurry.
