Question concerning paint code......

Just to add, I am pretty sure the T prefix refers to a Corporate color.. eg. TX9

T = 1962 .
TX9 ( Black ) and TB3 ( Corporate Blue / Petty Blue ['64-'71] / Super Blue [Dodge , '72-?] & Basin Street Blue ['72-?] ) both date-back to 1962 .

These 3-character codes are the last-three of Chrysler's supplier's paint part number .
