I made a 3D cad model showing the stock shock absorber, this allows you to see the inside of the assembly.
Please note that these are not official drawings from the manufacturer. The accuracy is limited by the simple measuring equipment available to me.

The CAD model can be downloaded as export in different formats here (STEP AP203, IGES, 3MF, 3D-PDF, EASM). The 3D PDF file is available both assembled and in exploded view.
