Fast forward 40 or 50 years and of course people have lost fasteners n the course of doing repairs and simply replaced them with regular old metric from the hardware store, thus creating a metric/SAE nightmare. My 69 Datsun Roadster required a complete set of SAE and a complete set of metric to do any sort of work on it.  |
Growing up in Australia, I learnt metric from a young age. Then I started my career in aviation and had learn imperial. Now I've got a garage full of both metric and imperial tools.
