there are four bolts holding the seat rail to the floor, undo those and the whole seat will come out (for ease of access to the seatbelt "catch/reciever") as for the trims, the rear seats have to come out, the squab (lower part of the seat) just pulls out... CAREFULLY! and then there are two 13 or 14mm bolts either side holding the top part of the seat in. then you start with the trim. the has several screws and clips you'll need to find before you pull it out. start at one corner and feel for where the clips are and again, carefully pull them out.
you will also need to remove the boot trims to get to the rear seatbelt reels. follow the instructions given in the box and do them one at a time. its mostly common sense.
as for the price, that sounds about right, i cant remember what i paid for mine but i got trade discount etc... so if your paying 260 for front and rear belts, then happy days
Its actually 130 for the RHS and 130 for the LHS. so if im just doing the two seat belts at the front, can i still remove the trimming without taking out the back seat? or is that trimming all one piece?
