I don't know if I still have the outline and course material any more. Three of us did a class for mature adults about 20 years ago. I remember that we started out with documentation and reference materials. Identification of exactly what you are going to work on is the first step. Making sure that you have legal ownership is second. With old cars and trucks sometimes the paperwork you receive with the vehicle is not 100% accurate. As an example I have a '18 Chevy 490 that is titled as a '16. The other numbers match but apparently when originally titled (likely many years after it was first sold) they wanted an '16 (first year for 490) instead of an '18. Then we went onto reference books, car clubs, museums, libraries that can provide accurate information on the vehicle.
After you understand what you are working on then the decision is how much work is to be done. Frame off, frame on, cosmetic, just preservation, upgrading, etc.? That should result in a "game plan".
After that you can then get into the major areas like: frame and suspension; drive train (engine, transmission, rear end); radiators & cooling; engine electrical (generator/alternator, starter, distributor); etc.
