I've never taken one apart but...
If they use the same boards, connectors, and other hardware it is
probably a drop-in replacement. However, you should find a group
devoted to this device and ask there.
I would not reccomend asking the seller of the replacement screen as
they might say it fits just to make the sale.

I'd say absolutely ask them, then if they tell you it fits and it
doesn't, you have leverage to obtain a refund.
