Link on the net to decode SS Chevelle ? wheels????

[Mr70]

YA was the 1969-early built 70 application.
AO was the one that followed it in 1970.
You are correct on the month/year decoding.
Look for another code to the left of the Valve stem and month code that will narrow down the year.
Looks like M4 with an 8,9,or 0 under it,
Decodes as 1968,1969,or 1970.
This helps determine for example,if it's a YA October 1968,or October 1969 rim.

the YA has MI
9


and the AO has M
9

Rick how do I read that..Is this info in the 67/69 Camaro Colvin Book??? I dont see how to read that info....Thnx for coaching me on this...

[Mr70]

Your YA is May 26th,1969 for a 1969 model application.
Your AO is Dec. 15th,1969 for a 1970 model application.
I use the Chevrolet Dealer Service Bulletins,and Service News for reference,among others.

Rick,is there a book or handout published a person can buy to decode the small letters next to the month...I would like to read all the info out there on the subject and get up to speed on the different codes...

Thnx Bud.

Hey Bud,

I believe there is a decode key for SS wheels in the Camaro book by John Hooper. I have it at home I can check it later for you. Or maybe someone else has it handy right now...

Thnx...question if you were going to buy one book to cover codes and correct information on 67/69 Camaros is the Hooper book the one to have or is there a better one...?? most of my stuff is very old....
