Need guidance on replacing the alternator.

[MattC0509]

I have a 2020 ST with 54k miles and recently had to replace the battery for a second time. Shortly there after I received intermittent warnings about checking the 12v charging system. This persisted for about a week with no issues start up or other wise. It became a consistent warning that came up every time the car was driven so I had the alternator tested today and it failed. I am in the process of replacing the alternator but cannot seem to get the old one free. Does anyone have any insight on the best way to remove the alternator and/or access the bottom side and wiring connections on the rear?
