Cracks in the mounting screw wells are very common in Bronco OHCs (and NOT common in Ex OHCs, for some reason), but easy & cheap to repair by hammering 2 washers into cups, and gluing them into the broken holes which have been drilled out slightly larger. I used E6000.

If you're looking for a Bronco overhead console, e-mail me thru my profile here or on almost any BBS dealing with Ford trucks or Crown Vics. I usually have a few. I also have extra washers if you can't make your own.
