I'm working on specifying the Autococker. I've done a complete pump and the pneumatic semi only needs the HPR and LPR. For now, I've made a blueprint for the front block and back blocks. Complete CAD of bodies are plenty, but the rest of the stuff is what's missing. So I will go and upload those that I finish. Of course these are my measures, lack any tolerance information and are, at best a guess.
If there is any mistake, it is my own. And please if somebody more knowledgeable finds an error or knows the spec better, please tell me so I can update this blueprints.
