It sounds like you have the typical blank posts. The windsheild gets put in through the slots, positioned against the brackets and set to the correct angle. Then you transfer the bracket holes against the posts to drill them, don't forget to mark them for a cut off length as well and radius them so you don't have a knee stabber under the dash. Pull it apart and drill and trim. Reinstall is a reversal of removal (I've always wanted to say that).
