Need help decoding my front windshield glass to see if it's original or not for 1970. I looked at a previous thread on side or back glass but it appears to be different.

LAMINATED AS-1 DOT 177
M52 A X
LOF
0 0 2 LNSG L
J Y

Thanks.

Safety-Plate is OEM glass
Safety-Float is replacement

There are 2 different letter codes in your data and I don't know which appies to the date

JY - May 1972
AX - Sept 1968
