opel six cabriolet 1936

Good morning, I am restoring a 1936 Opel Six Cabriolet, but I cannot find any technical data on the vehicle, so I would appreciate it if anyone who knows anything could send me an email - meil  the information about what I am going to describe   , such as how to adjust the front shock absorbers, what fabric  the   upholstery is made of and its shape  , and how the hood is attached at the back.
 Best regards
Paulo
