IMO, the old non synchro should have been put out to pasture immediately after the new full synchro came out. GM kept the old non synchro on base 6 cylinder pickups through '68, used the newer full synchro on optional engines during '66, '67 and '68. Finally in '69, all engines used the full synchro.
