Query: BEWARE! - Outdated, expensive information

I tried to order this book first from the copyright holder and authors, Electro Automotive. After I sent off my order, I e-mailed a question about the resources here in Hawaii. Whether anyone has converted a vehicle here using their components, etc. No answer.After a 2 month wait my check wasn't cashed and no book arrived. Nada. Guess they don't want to do business.So, being a glutton for punishment I ordered Convert It from Amazon @ $24,95. MISTAKE. I didn't read far enough into the reviews to see how outdated it was, 19 years outdated. While some of the basics may still hold, the components surely have improved with time.So, I can't recommend it for anything but basic, basics...and not for the price. And, by all means, beware of Electo Automotive.
