The Man Card prerequisite has a little known section which requires an applicant to set up at least one set of ring and pinion gears and bearings.
Mine was a 1978 Fiat Spider. Fun finding shims for that one. I will admit that mine worked out more from luck rather than skill.
I still got my Card stamped, never the less.
Good luck to you bart!
