Lol no it’s not that bad Greg. One door at a time if going for a full strip most of those parts come out as one. If its just the push lock it’ll unhook from the central locking mechanism No.39. Or maybe you can remove the reflector or window seal and pull it under the hole in the door.
Edit it also looks like the top is threaded so hold the bar attached to the mechanism and twist. Bar goes straight down to the mechanism from where it poke through, you’ll know it when you shove your hand in, give it a wiggle
I got the doors off by removing bolt 17 and then managed to press down the door lock and slide a piece of aluminium over it through the door handle hole below, then painted them.
