all the parts are easily available in plaza market. @brownrose78 pointed the correct shops. there are few more shops that deal in suzuki parts u have to search for them.
get all the lights, bumpers and door handles fitted before paint so that if any adjustment is required then it should be corrected without damaging the paint.
Dont miss the area behind the dashboard and the area where wiper setup is installed.
Check all the door water drain holes that these should be free otherwise if they are clogged then they will take rust.
check the pic, the circled area needs correction.
