Is there a teardown guide for a Samsung Ace S7500

A friend of mine just dropped his one day old Samsung Ace S7500 phone. The LCD is still working, only the glass has a huge crack from top 'till bottom.

So I searched and found a replacement glass on eBay, but I couldn't find any (teardown) guide for this type of phone.

Is a glass replacement enough by the way? Or should I look for an LCD + digitizer replacement?

Is there anyone who can help me out here?
