I've been collecting the parts, but I haven't actually done it yet.
From what I've read, you'll also need a new headliner (the black plastic part that goes around the manual latch and under the sunshades) and a motor mount plate. I'm unsure how the plate is mounted. The panel, pullys, tray, etc is all the same electric or manual.
One of these years, I'll get around to starting this project and I'll do a writeup with pictures.
