Bogdan,
Finding those from Italian club sites shouldn't be any problem on web or P2P (Emule). But finding one in your language is probably a bit harder to locate on P2P or some site.
You could contact some local Lancia service or dealer. Is there any chance that some local community or club of Italian cars exists in Ukraine? Prehaps you should look there. Or simply find some owner and make a copy. Sorry that I can't offer you some great links. Haven't really followed any forums recently. But good bet is also to find some large Lancia Internet club or community and they might offer better findings.
I'm sure Stefanel would be kind to copy his manual. But it is in French
