If you looking for the "Fiat & abarth tricks" book by Greg schmidt i know where you can find them,they are copies (from copy shop). It is bound and with protective plastic.
Send me a personal message,so can i tell you the email adress.
Every now and then a copy of this turns up on Ebay.
I have a project underway at the moment to publish a series of e-books. These will for the most part be "technical dossiers" of original design and specification documents. I have found a source for much original material dealing with engine and transmission specifications for Abarth cars. I have thought of including Greg's document as well. This project should get off the ground later on this year.
