T42P needs parts

[crab_rangoon]

Hi!
I've got a 15" IBM Thinkpad T42P with lots of cracking on the plastic case which I'd like to fix/replace. The screen is good, the motherboard is good... it's just the lower case that needs attention.

I'd like to find a broken/for parts unit and salvage what I need. Which model could I buy as a parts unit and swap this thing's motherboard + screen/lid onto?

I'm imagining i could find a T41/T42/T43 but i'm not sure what would be compatible. It's not too likely I'll find an exact model match for me to get parts from.

What I've got specifically:
T42p 2379-DYU, 15" flexview IPS UXGA, 1.8GHz dothan, 128mb FireGL

You can use any 15" T41/T42/T43 model and scrounge/swap that for parts.
These parts are all interchangeable (except integrated or discrete fans).
You can also get manuals for doing this from the HMM link above.
