I have a spare rebuilt Aussie gearbox, dated G23 1 for July 23rd 1971. It has a Holden 899 cluster gear and 544 input shaft.
Would this be date correct for a CK XU-1? Also the input shaft, although genuine Holden, has no grooves instead of the two grooves it's supposed to have.
Is this an early M20 thing or a replacement Nasco shaft?
Cheers Kev
