1965 Los Angeles built cars information needed!

This car assembled B20 November 20th, used PNT on the fendertag compared to Patch's car assembled C09 December 9 which had the new PAINT stamped pn the fendertag. In between those dates the change was made. Any more tags between those dates woild be great to find out which week the started the new stamping.

The reason for this seems to be more and more cars had so many more painted related info that the old three letter stamping just could handle a three letter/digit code while the stamped PAINT could handle a fove letter/digit code.
Just look at Bob Jasinski and pishtas Barracudas. They all had a five letter/digit code.

This means that sometime during this time the assembly plant in Los Angeles changed the stamping on the fendertag. I think I need more pictures of LA assembled car during this period to get the exact day.
Thanks for all the help.
