Part number needed

Hello all,
I've already posted in the wanted section but just in case, I'll add it in here too.
I'm looking for this part but for the drivers side.
It's missing and I've not been able to identify it on the parts lists I've seen so far.
With winter coming I'd like it covered properly (like it's going to make a difference )
Thanks.

I can’t tell if it’s an index finger. Have you a picture without the Land Rover in the way?
