Replacing screen on PS Vita PCH-1001

My son and I are looking to try to repair his PS Vita 1001 where the screen is no longer working due to a fall. I'm having trouble finding guides or replacement screen parts for this screen.

Any info available to do this? Appreciate any help.

 

Replacement screens could be found on aliexpress.com or on ebay. Here is a teardown of a Ps Vita.
