Diesel 1.9 hatch back Rear seat swab brackets

Hi there,

Quite how it happened I don't know but both the brackets that hold the rear seat swabs ( the ones that to the base of the floor not the clips on the up rights) are snapped     Two questions, are they easy to remove ( I've tried before and failed).  Secondly can anyone direct me to someone who can supply replacement brackets.

Thanks a bundle
