2015 4 900 Polaris Aluminum Doors, need info

Trying to decide if these are the doors I want. On the Polaris Website it says these are the Aluminum Lower Half doors. To me this means they are just that, only the lower half door that attaches to the factory door.

Polaris Item #2879943

Aluminum Lower Half Doors – Black | Polaris RZR Store

If these are indeed the full half doors as the picture shows, do you reuse the factory door frame to mount? I would like to keep my PRP door bags if this is the case.
