Chuck, I have two 8L27's which is Dec 27, 68 if you are interested in a trade.

I thought M was DEC and L was NOV for alt dates because they did not use the I for a date

According to Colvin's book, K is Nov and L is Dec

On which components did they use M as the date codes?

Starters,alternators,distributors. Ive seen M date codes on 186 heads but those are errors on the assembly line i believe.
