I didn't take a ton of pics eary on into the retrofit, but i'll post what i've got.
And ya, if you do it like me, permanently mount the projectors, make sure the aim is perfect.... left to right, up and down, and rotationally (the automotive lighting faq and daniel stern's website both describe the procedure well). I found a loading dock about .5 miles from my house that was pretty even and flat, used it to prefect my aim over several nights...probably made 10 trips there and back per projector.
Obviously details will be different based on which projector you use, and it's dimensions, as well as wether or not you keep the stock high beam...if not, you can just pull the whole reflector bowl assembly.
Pics of how i cut the housing:
Pics of the lamp seated in there:
Some pics before i sealed up the front or back:
And Dion put a bunch of pics of his set up in the old how to thread.
