Coverley - Production Engineer} is sending you drawings showing how we have arranged to fit the standard 20/25 synchromesh gearbox to the J.III unit. We think this should be standardised in order to save having to fit the special first motion shaft in J.III cars, all the parts now being interchangeable.
