After some considerations I decided to remove the entire insulation for better access to the airframe. This makes it easier to remove remaining wires, tubes and other unnecessary equipment. I am still missing the footrest brackets, panel brackets and panel hinges which I will have to re manufacture.  

D-ABUD/N707QJ is undergoing a thorough cleaning and removal of insulation, wiring and unnecessary tubes. Kitchen cleaner is probably the best cleaning product to use for this job. Note the large amounts of nicotine which were not that easy to remove and required some extensive rubbing.  

Control coloums removed, Foot rest removed, wirring removed, Panel brackets removed, cockpit floor wire duct removed.
