LCD Display Replacement model number question.

I am trying to replace my defective LCD display. I'm not going to go through the trouble of trying to locate the problem and fix it locally.

I noticed that the model no. for the Macbook Pro 13" Unibody Mid-2009 is 661-5232. For the equivalent Mid-2010 model, that number is 661-5558. However, ifixit.com and a number of other websites sell complete LCD displays for mid-2009 and mid-2010 models as one type of display (as opposed to the 2011 and 2012 models).

Does that mean that if I were to get my hands on an LCD display for a mid-2010 model (661-5558), it would be compatible with my mid-2009 model?

FYI, most sellers (not ifixit.com, though) state and sell LCD displays as either 661-5232 for mid-2009 Macbook Pro 13" or 661-5558 for mid-2010 Macbook Pro 13".

Just wondering if there's even a difference or if it's just a number thing. Thanks for your help anybody!
