Hello!
So I have finally got my hands down to write about my experience with the repair.
I'll start with what was originally on my car. Apparently somebody has already broken it before (which is fairly easy when trying to exit the car!) and what they came up with was this a bit messy epoxy solution, but it did work. Also I didn't even notice it when I was buying the car, it is really hidden!
So I bought off this new repair kit, which seems to be manufactured just one year ago! (I have also recently replaced power steering pump, and the one I got from Jaguar Heritage was manufactured in May this year)
And now what's in the bag, for those who are interested:
The replacement procedure is fairly easy -- unscrew everything and then crew it back in

(but be careful with some old plastic bits, old ones can break, as did one of the screw fixings of the front lid in my case)
I am not posting any pics of how that looks when repaired, since it simply looks normal
