I would very much like to have the factory manuals to rebuild 1600 and 1750 engines (1966-1968 Duetto and Spider). First, are there separate manuals for the 1600 and the 1750 engines, or are they combined in one manual? I hear a lot of talk about how good these are, about people having friends email copies to them, etc., but I have not had any luck in finding them myself. Where can I get these? If anyone has e-copies they'd be willing to email to me, I would really appreciate it. Any advice will be greatly appreciated! Thanks in advance.
