M74 is not the date code, M74 designates that it's a Corvette side window.

The date code will be 2 letters...the first designating the Month, the second designating the year.

Example: JL =May '74
The months codes are:
N= January
X
L
G
J
I
U
T
A
Y
C
V= December

Year codes are:
Y= '72
U= '73
L= '74
