Just looked at your post re dog gaurds and googled barjo.. and i see what you have to fit..
to remove these panels in the zaf A , i had to remove the plastic trim above door (held on by 4 metal push in clips)
pull off the white panels window surrounds that again are held on by metal clips (push in)
remove the door bottom trim (just inside door on floor ) 4 screws..
remove rear doorrubber draught excluders where it covers plastic panel that you want to remove..
there is 1 screw to undo inside the access panel to the rear lights
and 1 screw at rear of panel that is visible.
and 1 screw inside where the parcel shelf fits into(the square hole)
then 2 screws at top rear of panel inder hwere you removed the rear panel over the windows(white one)
then it is fitted with metal clips again
all the clips fit in olbong holes..
hope this helps give you some sort of idea
