Hi! I know this is a little late to be posting this on this ancient thread, but maybe some people will find it useful still:
LitterWorks maintains a listing of assembly instructions on not only their cabinets, but their DIY kits and other LitterMaids and such. Maybe some of the information you are after can be gleaned from those? They are all PDF files, so make sure your Adobe stuff is all up to date....

There is a replacement chute all by it's lonesome... wonder what that could be handy for?

Although you might have found these all on your own, i think that at least having the chute would help your litter box from looking too crazy, with the foam and super glue and what-not! (I'm talking to you morris....)
I think if my boss knew I posted this, he might be mad.
