quote:if I am correct , my /1 ZF would have .846 fifth gear
Yours should have the .705 fifth gear ratio. My #1490 has it. There is a placard attached to the side of the ZF that shows the ratios. The earlier 71's had the .846 fifth gear. Your build date should be 5/71.
The "'72 in the papers" probably means that your car was first registered in '72.
