im  a bit confused now. from what i could find, my car, #65002, has a mfr date of 1-72. now i have found this http://zhome.com/IZCC/ZRegisters/VintageZ.htm 

which shows #66068 as a mfg date of 2-71. so what do i go by? there is no door post tag on my car.

thanks all    sb

I would say yours is a 1/72

I bet that's a typo, 2/71 should be 2/72.  Mine is 2/72 and 69,***.
