TR6 What year TR6 cut over to Type-J O/D?

Is there is a specific cut over year, or was this done on a rolling basis?

Thanks!

Late '72 (model year '73) with the CR/CF commission numbers.

Lots of other things had to change at the same time, so definitely a specific cut-over point. Among other things, the speedo calibration changed (even for non-OD cars) as did the speedo head style.
