Thank you xxxavier2k and skperformance for both your replies. I really appreciate it. So if I understood correctly, I can access the 'metal' clips by taking off the 'internal' body panels i.e. an entry is to be made through internal door panels (leather/plastic) to access the clips that are holding the outside/external door cladding in place.
If thats that case, then I should be good since I picked up the haynes manual and it explains the procedure to access the internal door panels.
