Hi guys..
The mirror on my drivers side wing/door mirror has shattered, so I need to replace it. I have found this on ebay:

http://www.ebay.co.uk/itm/FORD-FOCUS-98-04-ELEC-HEAT-DOOR-MIRROR-GLASS-RH-NEW-/160645730679?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item25673b5177

Does anyone know how I can change the mirror pane.. take off the old mirror and replace it with the new one?.
Or am I better off changing the whole wing mirror unit?
My car is a 2001 mk1 focus 1.6 ghia, with heated electriv mirrors.

Thanks in advance guys

Its a pain in the ass to remove it, but as its shattered anyway you can pry the mirror out and just push on the new one!
