Hard to say if they're really NOS or not, but that is the part number for GM trim rings.

 

Thanks Joe , the guy I got them from had several NOS gm parts that he picked up these are the ones I needed for my 69 z

 

Hey , Also I bought 5 gm center cap derbys and on one of the boxes it says....Return
Return
Reason Code:
21
What would this be?

 

Don't know what part number that is...

Recent thread over at CRG: http://www.camaros.org/forum/index.php?topic=7467.0;all

The numbers below are all from the 1972 GM parts book.
14 by 7 wheels
In the blurb below The first number is the replacement second design part number with the improved and safer clip design. The "sup" superseded number is the part number before recall - the design with the "suicide" clips just for cross reference.
So we have this info for 2 1/4" rings:
3934892(sup by 475020 inside clips) - 1969/ALL WITH 14 IN STD WHEEL /OPTION P06
3934892(sup by 475020 inside clips) - 1969-71/ALL WITH 14 IN RALLY WHEEL /OPTION ZJ7/ EXC 350 /300 HP/ AND 396 ENGINE

And we have this info for 2 3/4" rings
9796919 (sup by 2251945 ring clips) - 1969-70/ALL WITH 14 IN RALLY WHEEL /OPTION ZJ7/ WITH 350 /300 HP/ AND 396 ENGINE
9796919 (sup by 2251945 ring clips) - 1969/ALL WITH 14 IN SUPER SPORT WHEEL /OPTION N66/

To me that reads that for the 69 Camaro the 3934892 ring was used by standard 14" wheels and rally wheels EXCEPT for the 350/300 and 396 engines. Which means to me non-SS rally wheels, ergo 14x6 Rally's.

And the 9796919 ring was used on the N66 rim (SS wheel) AND option ZJ7 rally WITH 350/300 and 396 engines (SS models!)

But if they are in GM sealed bags they might be NOS, but all the ones I have ever found are in individual boxes not a full set in one box.

 

You may have bought a 4 pack that came in the trunk, instead of a part number meant to be sold by a dealer. The type of attachment will show if they are originals or replacement type.

 

My body man worked at a gm dealer and says they may hve come in the trunk and never put on.

 

:thumbsup:

So I assume by the paper notice in the bag with the rings that the rings you have are post safety recall, and are the late 69 redesign clip all the way around?

 

yes
