hi roy,60 quid is well over priced for what is now a obsolete part for your servis.I managed to track one down for you at $34.52 ,from www.apart4u.co.uk .the seal is easy to remove and install .to remove = start in top corner,simply prise seal out of door void locator ,by simply pulling ,you may need to prise out with a sharp knife ,just to get it going.refit new by starting in one corner ,just angle the seal and push flat,you will hear the seal snapping into the door seal channel in the door .if you struggle to refit new use a small amount of washing up liquid . hope this helps.
