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

[budnate]

I checked the Colvin and it says they are 1969??? rims..I guess???..I am a dope when it comes to decoding rims..only since I have been around here did I understand how important it is to a nice car to have the right codes..what I found today is

4- 14X7 SS rims

coded
3- 12 valve stem 15 AO
1- 5 " " 26 YA

The book I have if I am reading it right says they are 14X7 JJ rims and the side note is the AO rims supercede's the YA rim....did I do it right...??? LOL.

so the first number on the left is the month and the one on the right is the day....are the codes ever re-used where there would be confusion on the proper application/year

Guy pulled them from a '71 so I assumed they were 70 rims and new I did not have book for a '70

Educate me on the subject please....

Thnx Bud.
