I have a 1990 Bronco II. One hot day 2 months ago I went out to get in and out of nowhere the driver side window shattered. I bought a window from a salvage yard and now can't figure out how to get it in. Does the regulator bracket at the bottom of the window have to be removed and re-poprivited or is there some combination on how to get it down into the slot into the tracks with the bracket still attached?
