as for getting them i use this ebay seller to get clips etc:

ask them a question for the part number and they can give you a price, although so can any peugeot dealer.
Although despite the new clips i still get a bit of a leak from up around the A pillar corner, i think water gets in under the door seal, its definatley not through the sunroof, the windscreen is ok which leads me to believe that seal needs something behind it.
