Logic Board Compatability

As a recent post of mine explained my logic board in my late 2008 2.8ghz macbook pro has died, bad times.

I can't find one of these a a reasonable price, as such does anybody know if a mid-2009 2.8ghz logic board would fit/work?

The only difference I can find is that mine has an expresscard slot, and the mid-2009 version has a SD card slot, how that effects it I am no sure?

 

Model numbers are vastly different, don't know if that is significent:

mid 2009: 661-5213

late 2008; 661-4836
