go down the old fabric shop and you can buy the black material strapping that you can replace the old stuff with on the edges. the old ones pull straight off you can either machine them back in or using a hot glue gun and i mean leaving the gun sitting for half an hour to get it running hot, bonds the new edging to the carpet with no glue showing. clips back up them or you over lap the material on the door seems as per orginal then trap under the door edging rubber. mine were knackered, pulled the carpet back a treat and unless you looking for stitch marks cant tell, costs ?8 for around both bottom door edges.
