Well I got my passenger window motor installed today. I tried both versions in this thread:

First without separating the motor from the bracket. I believe people when they say it can be done, but I couldn't make it work without forcing it. I had to separate the motor. I put the motor in first, and then I had to insert the track/bracket(without the z tabs) in the door from the top middle hole. That was the only way for me to get it in the door without force.
Other than that, it assembled in the door without major problems. I tested it just now and it works beautifully!
I opted to use garage door lubricant (almost clear in color) on the guides.
