no need to get new parts just open up the trim panel and get old retractor out the problem is probably with the coupler to retracting tape rivit it has probably riped through the tape. drill out the rivit which holds the spool housing together and get tape out from spool and fold end over the coupling and rerivit the tape to the cable then re rivit the spool housing (its like a tape mesurer) or use a stop nut and bolt as spool axel.
