I also replaced my window regulator but I didn't have a PDF file (I'd like to see it someone has it). Once the old one was out the new one was impossible as a exact bolt-in. Ultimately, once I got it inside the door, it worked best at an angle. Just a slight tilt upwards made the difference. I then repositioned the support brakets to line up with existing bolt holes. The whole unit works like a champ. Only thing is that the right side rolls down a lot faster!
