The 2.16 board you found may or may not be a core 2 duo. It could be a core duo and unsuitable for you.
This logic board, a 2.33 Core 2 Duo will drop right in with no problems: MacBook Pro 15" (Model A1211) 2.33 GHz Logic Board
Although iFixit currently has it listed as "out of stock", I would contact them here and ask for one as they may have it but not gotten it to the inventory list yet: http://www.ifixit.com/Info/contact
To be sure all this is correct, please remove the battery and look in the compartment and its side walls for your exact model.
