Outside passenger side door pillar (gloss black)

i have purchased a new one to replace for cosmetic reasons. This is starting to look complicated, as i cant find any instructions for removal. I see what i think looks like rivets, rather than screws, and it seems like the door panel has to be removed to reach the lower attachment. Can someone guide me.
thanks mike

Mike; I have no experience of this, but, in similar circumstances, I would see if I could locate an exploded diagram on one of the Jag parts websites. I have had good success in the past getting them from my local Jag dealer’s parts department.
