THIS FILM INSERT is NOT a complete film back, it is the FILM INSERT ONLY, you'll need the outer housing to make it a complete film back. Most of the outer housing doesn't break unless it's dropped, but the film inserts are more delicate as all the winding mechanism and gears are inside the film inserts). If you already have the SD 120 6x7 film backs but the film inserts are broken, then this film insert is the replacement you need.
