Help with Chevelle ss wheel dates

[chevyman0429]

I have a set of 70 Chevelle ss wheels that I'm looking to part with and need some help on dates. Thanks Gentlemen

I have three of these M5 2. 18 AO and one dated MI. 1. 20 AO all 4 of them have a zero stamped under the letter M

the 0 under the 5 is 1970 and the dates are Feb 18 70 and Jan 20 70. The break down is month day and the number under the M-number code is the year the wheel was made. hope this helps, Andy
