Default Early 1969 ZH or ZG nodular rear axle unit

Date code October or November 1968. Prefer the cast numbers be readable and the housing not be badly rust pitted. May consider just a housing, as I have a 3.55 chunk.

Would also consider ZG 3.36 complete.

Little late for you at 342th day. Think it’s a 3.31?

Still need a ZH dated Oct/Nov 68. Would consider first week of December, car assembled 12/17/1968.

Added a wanted post in the OHC/Sprint forum, as a 69 Sprint parts car would have been factory equipped with ZH.

My old 1970 trans am had the original rear end in it, and it was built only 7 days before the car. It was the closest date code on the car.

If you have access to contact info, can you send to me in PM?

Another bump, would still like to find this unicorn. I found some old posts referencing p/n 9795107 as the casting number.

Its always been my understanding that a 4 pinion with safe-t-track would be Nodular.
Isnt that true?

If you do a quick search on the word "nodular" a couple dozen posts come up, going back ~15 years or so. Lots of good info for both A and F cars.

Rears were only nodular if the HD Saf-T-Trac option was ordered.

3020 was the number before the 5107 I forget when the change over happened.

I believe that 4 pinion were also only if HD was checked so what he’s saying seems. Correct to me
