Thanks for that one! I know of serial # 3844335064 which may have been built the same day or the day before on the lines at Oshawa, Ontario! It appears that the chassis was assembled by Holden's and I wonder if it was in the Adelaide plant as they did not it seems use "A" which was their plant code, whereas Brisbane, Melbourne, Perth and Sydney used "B", "M", "P" and "S" respectively. However each plant had its own mind as to how the designation should be applied or not, so don;t quote me therefore!
