I own an 84 626 deisel. And anytime I go into a machanic and he asks what kind of car i have he's like "Holy crap, i've never herd of a 626 deisel!" There is hardly any information on the internet on them so I was wondering if anyone know's:

Where to find a shop repair manual(not that it ever breaks down)
basic specs i.e. tourqe, hp, ect.
and especially how many were made?

Any information would be awsome, thanks.
