1969 Volkswagen Beetle Tech Specs

How tight am I supposed to tighten the Beetle's rear axle nut? What weight oil should I use? How big is the nut that holds the steering wheel on? Instead of flipping through my small library of Beetle books every time I need one of these pieces of information, I decided to start a little tech sheet of my own. Hopefully it will expand as time goes on and I run across more information for it.
