Replacing LCD and digitizer, does version matter?

view full story

http://forums.androidcentral.com – My coworker dropped her HTC EVO 4G on a tile floor and destroyed the digitizer and the LCD both. I have read online that there were different vendors for the LCD during production of the EVO 4G. Do I need to find out what this phone shipped with before I order replacement parts or is it irrelevant? Thank you and sorry if this has already been covered, I did search first but may not have used the proper wording. (HowTos)
