Been tinkering with this thought in my head...

When a 1969 Camaro is being ordered, then built along the assembly lines, How long did it take K-H to make the rims to get to the car?

I wish to ask the timeline and process for rims to reach tires then reach the car being assembled.

Is there any timeline differences for the same questions above pertaining to Van Nuys vs Norwood plants?

 Huh

K = Kelsey Hayes (manufacturer of the rim for GM-Chevrolet)
1 = plant at Romulus, Michigan (for GM-Chevrolet)
9 = 1969 (Year of Manufacture)

Now, as I am searching around for info, in prior years of 1969...
KH rims being manufactured for Chevrolet, in my image above,
the earlier rims only used a single J after the rim stamping of the size and width.
Example :  14 X 5 J
Does the single J denote anything towards how the rim fits the brake system?
Where as, in 1969 JJ stamping, does the JJ represent anything towards brake system fitment?

What is curious to me is if the early 1969 Z28 AD rims were stamped with JJ or J ?
I would assume the the YH rims were having the JJ satmping.

In my image above, you will notice the letter A below the 14 of the 14X7 JJ stampings.
I am going to guess that this denotes the month that it was made.
This image is from one of my YJ rims in a set from January 1969.
To add, there is also a letter in the wheel center that seems to denote the month of manufacture, K-1-9 A.
On this particular rim, the A is stamped just under the GM stamp on the wheel center.
I am going to assume that the outer band was manufatured in Jaunary, 1969 by looking at this.
I am going to assume that the wheel center was manufatured in Jaunary, 1969 as well.


I decided to go and look at some of my other rims.
K-1-8 trhru K-1-9 issue.
Some of the K-1-8 rims have the Letter code in the wheel center on another of one of the 5 landings of the rim where it it can be stamped.
One set, stamped for October, 1968 denotes a 10-X date.
These rims show a K-1-8 with a Letter J.
Counting out the months, J lands on the month of October.

Thoughts....

I've noticed some similar correllations in the past, but have seen nothing documented about it..

Could be releated to the different dishes in the centers for drum/disc brakes, 14 x 6 ralleys came in a few different offsets.

Just to add to this discussion...

Found an image of a 1967 14 X 5 rally rim from a Nova that is stamped JJ on the band.

My 05A 69 Z-28 has YH rally's dated 4-21 and either 4-24 or 4-26. It has been a while since I looked at them.

Maybe this s a good time to begin a K-H rim submission.

Maybe we could start a thread per coding:
YH rim thread
YJ rim thread
XT rim thread

Maybe a month by month categorizing.

If you are able to get the wheel center and band codes, that would be great!

The following pic is of a Oct.68 "AD" rim. I don't believe the "A" is the month. Under the "JJ" is a "10". I believe that is the month. It would be nice to see you include the "AD" rim in your research.

The "K", "J", "JJ", and "JK" stamped on the rim following the wheel size are unrelated to the brake system fitment - that's determined by the contour of the spider, not the rim. The letter stamped as the suffix of the wheel size is the SAE code for the drop-center contour of the rim cross-section, including the presence/location of the tire bead safety rib(s).

Were Buick ralleys stamped the same as chevys? (yes Buick, They came body color with small caps with Buick crest cap centers)

There's a good note describing the number scheme used by Kelsey Hayes somewhere.. maybe someone here has it handy and will post it?    I think I'm recalling correctly that the '1' after the K..  is the code for Chevrolet.. so maybe it's a '2' for Buick?  or ??   Smiley

All 5 of my rims are K193 25YJ. My car is 04A Van Nuys. So the timeline from wheel stamp to car body is pretty close.
