You could try matching your exact model with results found here:

In Europe some offerings of OWC (macsales) are available in the

region; http://owcshop.eu/catalog/ including the UK; also note

Also the powerbookmedic site has parts for a variety of models:

Companies whose business is to repair & restore portable Mac

computers usually have a parts supply; some may share them

with a hobbyist. This one offers substantial repair/parts service:

Be certain of your build model so as to match up correct parts

and alleviate assumptions that may be based on fuzzy logic:

• Mac Serial Number lnfo - Lookup your Apple Serial Number:

You can get a download of a database of Apple/Mac products

that's helpful, from application maker's site: http://mactracker.ca

Also note http://www.everymac.com site has much information.

So if you correctly identify the build model year & hardware spec

locating replacement parts of correct match should be easy. And

note the size of the display can play an important role where parts

and upgrades are concerned. Details: specifications do matter.

Then, there are guides to replace hardware. Some fair video are

available to use free, from OWC macsales site. • Install Videos

And the generally well-known iFixit repair guides cover Mac tasks.
