As he said.......look on ebay. I don't have the computer version.
I might buy one sometime just to have, but for me a book I can hold in my hand works best. Look for the blue shop manual for the 67 it will do well for you. Somebody on ebay sells them regularly new but they want forty dollars. It might be worth it but you can find one for less, and if you look patiently for a used one they can be had for ten to fifteen bucks.........Keith
i have both detroit iron and the cheapy 15.00 dollar one as well and i prefer the detroit iron manual. more expensive but worth every penny. much more comprehensive and easier to navigate and good tech support.
