Manuals and Technical Books might cover a lot of stuff that you already know, but knowledge is power, make sure you have the correct information when putting together your next dune buggy project. Two of our favorite manuals are the Baja Bugs & Buggies book and the John Muir "Idiot Book". Sure they are manuals but you can actually read through them like a book.
If you want to build an engine from scratch or rebuild your current engine the HP Books How to Hot Rod your Volkswagen Engines and How to Rebuild Your Volkswagen Engine should be sitting on your work bench. The welding and carburetor books are helpful for honing your skills as well.
For year and model specific books the Bentley Official Service Manuals have the most in depth information for any given VW. Keep your garage library stocked with all the manuals and tech books you will need. Or get one for the friend that keeps asking you to come over and help with thier project.
