You could contact specialists such as wegenermedia, powerbookmedic,
& others that repair computers for a living; some have a parts inventory.
The iFixit site shows some of the taken apart Apple portables and at times
will show part number references that may be used in some instances to
look elsewhere for other similar items; most won't be compatible across
the detailed build model series of their production run.
There is a lookup link in powerbookmedic site, similar to the serial number
lookup previously posted; I found their link will be somewhat secure if your
browser supports https:// but not always. The actual need to identify your
own product may not need to go beyond Apple support information, or that
found in the mactracker.ca download database application.

http://mactracker.ca - free database app for most mac products, works offline
http://everymac.com - has much info and also links to parts sources
As spudnutty said, these likely do not share (many if any) parts; buy from those
vendors who test what they sell w/ guaranty, those with a fair return policy, too.
Some batteries and power adapters may work, be sure to read up on that.
