Power Window Motor

89 Park Avenue - I can't see what's holding my window motor in. I drilled out two rivets and the motor is hanging by a long thin assembly that attaches at the top of the door. Is there a site on the web that shows the inside of the door so I can see how it's put together? Lacking a picture, are there removal/installation instructions on the web? Lacking either of those, can anyone suggest the best shop manual for this work?
