what year?? the floor mounting brackets changed a bit. over the years, the early ones mounted flat to the floor, later ones the front two bolts go into the front of a hump built into the floor.
Is it the seat itself or the brackets the broke? if its just the floor brackets I have a set from a drivers seat here you can have for free, they are the later style. that will at least get your seat mounted again.... if its the bracket that broke.
