Those are the serials of the engine and the car, giving you year of manufacture, but you need also to ID innards and things like clutch lever and mount because so many have been hot rodded...this old post I put together lays out most of the identification to fully deconstruct the transmission and its history. Van pelt's site will give you the serial # breakdown, and his book is the best on rebuilding.
