Desert ship

Moin. I would like to free my older sister’s desert ship from coarse rust. She loves her “camel” and I want to do her something good. It is a W463 from 04/1990, 6 yl., 238T km, silver, ram protection, afterwards equipped with black leather, a new roof including original sliding roof was probably installed. I have a few simple disassembly questions: How to dismantle 1. the thick decorative strip at hip height 2. the rear lights 3. external handles at the doors 4. external rear door handle (d 5. this black roof strip around the “rain channel” 6. Running board and bar at the lower edge of the entrance a. Are there any problems with the installation of the door handles regarding the central locking? Look forward to answers. A book (“How do I help myself” would I only buy if all the above mentioned points were included. Thank you very much. JH
