From there it is as nhusa said, depends on what you plan on doing, which job the tool is needed for. Don't just go out and buy the tools, study what they sell for. Lots of times tools are way over priced because sellers think they are rare, ok some are but most are not. If you get a T, get the "Model T Ford Service" manual and an owners manual for your year, can be gotten from the parts dealers. Also get parts catalogs, Lang's, Snyder's, Chaiffin's etc. They are free because they want your business. The dealers also sell repair books for different areas of the car, engine, transmission etc. They are put out by The Model T Ford Club of America.
