Quadrajets from 1986-1988 are virtually identical as far as I know on the 307 for the brougham and most cadillacs with olds engines. Anyway, there's a parts blowup diagram of a few diferent carbs complete with parts lists. I also believe it has a general guidelines section somewhere on there.

Also, there's a PDF version of it which is 180-some-odd megs. VERY handy for printing the thing out for a carb rebuild in your garage.
