The replacement is pretty straight forward, especially if you take a screen with the digitiser already attached.
For the model numbers it is best to ask the seller if he knows about compatibility.
It is quite possible that the end of the number specifies the type of the connector and where it sits.
Or that it needs a specific driver chip.
I used a few scrrens with slightly different end numbers on 720 and 730 models and only one it did not match the connector and one display was with an added black border inside, making the effictive size a few mm smaller.
