how did you learn to work on cars?

Yup. Thinks broke. I learned to fix 'em. Read books. In 70, when I bought my first 69RR, I bought a shop manual, smartest thing I EVER did, and of course, other books. When I bought my 70RR from a friend, he already HAD the shop manual, so that detail was taken care of. In fact, I still HAVE (somewhat torn) my old 70 shop manual. Have had it since around 71-2

The internet has been a giant help. Although there is bad information, there is all that in some of the books and magazines, as well. Hot Rod, Car Craft, others, have made some giant mistakes. Who was it had "Project X" I think the same mag had some "project coupe" which they got into one HELL of a mess with bodywork (incompetent shop) and I also remember that car, they took the driveshaft for shortening, and the "machinist" did a big blab on "how you cut it in the middle !!! ??? !!! of the tube.
