I would just buy the correct kits for your application....I don't see how you're going to save money trying to research each bolt yourself.
This manual you speak of won't help you find the correct fasteners, most are not even available with the correct markings and such.
It will tell you what was there from the factory, but doesn't tell you where to buy them. The people who have put the kits together, for the most part, have done the research for you.
