Hi Austin, do you have access to the Bentley manual? There is an electronic copy online- the link is somewhere in this forum. Your best bet is getting a physical copy.
Are there any visible bolts holding it to the floorboard? If you are looking for an OEM replacement, I have an assembly that I could sell to you. PM if interested, and I can also investigate how it's held down (both on the car, and in the Bentley).
