Prep was pretty easy. Grind the crank down to clear the input shaft on the tranny, fill three holes, and as a last-minute surprise, grind off a flange where the alternator should mount.
I was worried about figuring out which holes needed filling before I did the swap, but once you've got them both sitting side by side, it's really obvious.
I used the Ford shop manual on CD, with occasional reference to the Chiltons book.
