What is compatable with Sony VAIO FX410

Hi all - I have a Sony VAIO PCG-FX410 laptop. It is a fairly nice
machine and has been a workhorse for me over the years. The display
went out about 2 years ago (so I hooked up an external), and the
keyboard has some broken keys.

I would like to look around for another broken laptop to scavage parts
(since I just replaced this one, I can "play" with it now), but I have
no idea what other Sony models may be compatable. Sony website, of
course, is little help. I do not want to just shoot in the dark on
EBAY.

Any suggestions for how I can go about finding out what other laptop
models may have a compatable screen, a compatable keyboard, etc?

Thanks for any help. I do appreciate it.
