distributor and 12bolt date codes for a 09D car
« on: February 04, 2016, 12:39:07 AM »
I have an O9D Z28
looking for a date code correct 1111480 distributor, and a 12bolt.

the trim tag is 09D and the engine stamp agrees.

question is - how early could a 12bolt be to be accurate?

and same with distributor? 

thanks

09D of 1968, or 09D of 1969?  :)

Note:  my differential is 3 weeks ahead of the car; my distributor is 3 months earlier than the engine (which is earlier than most I think)...  but there's no magic date.. parts were not installed on a FIFO basis.

very helpful - and I've seen that 9E16 distributor quite a bit - so i'm guessing they stamped a TON of them on the same day for future production... just wondering if other was a later batch.

Yes, the 480's and 937's are batched...
FWIW it seems as though rear ends were the closest dated assemblies for 69's I have personally worked on or seen more than 20 cars with rears dated with-in 5 days of shipping dates.
Here are 4 off the top of my head...
 
69z        10D axle 1031
69yenko 01B        0119
69Z        04C        0418   0423 ship date
69L78     05B        0505
